When to Replace Your Running Shoes – Part B

This is the second part of our discussion on the topic of When to Replace Your Running Shoes

George A, Pelham, NY: This is a very important issue. I think many overuse injuries are caused by worn out shoes, and a new pair of shoes is less expensive than a few doctor’s visits. It always takes a little while to “break shoes in” before they feel comfortable, and then there’s a natural inclination to keep running in the same shoes. I usually use two or three different pairs of shoes each week, and get new shoes when I notice back or knee pain with one set of shoes and not another. Since it’s a good idea to give shoes at least one days rest between runs, it makes sense to run in at least two pairs, so the pain test can be fairly infallible.

The Pooch, Wendell, MA: You missed that huge study that was done in Switzerland in the 1980’s, something like 5,000 runners were surveyed. Granted, this was a correlative study, but running injuries were correlated with weekly mileage and previous injury history. There was no evidence that newer or more expensive shoes prevented injury, and some fascinating hints that runners in older or cheaper shoes had fewer injuries. Not the kind of result that shoe companies want you to hear.

I would propose that running form, and overall health, and much more important to preventing injury than what kind of shoes we wear.

Michaelmross, Boston: If Ms. Davis runs 100 miles a week, there would hardly be any need to “estimate” when she puts 500 miles on her shoes. As for them smelling, that seems unlikely after 5 weeks. As for putting them in the washing machine, doesn’t she know they’re held together with glue? – and, after you’ve done that: Yes, you have to throw them away.

Pharmguy, Bermuda: After 45 yrs of running i have learned that I should buy light stable running shoes.

Rotate among 2 or more pairs. Get rid of them when they dont sit flat on a table
or the last starts to curve. Last breakdown usually occurs with shoes I love too much after higher total mileage.

American in Tokyo, Tokyo:  The article puts forward a variety of analyses and opinions but in the end is inconclusive.

When I was in college, I used 1000 miles as a rule of thumb. At that point, the more fragile uppers showed signs of wear and tear, and the cushioning did seem to be less effective.

Most recently, I bought a very heavily cushioned pair (not easy to find). After about 600 miles, they still have a lot of cushion. Even if they don’t, didn’t many of those who commented say that cushioning was doesn’t matter? If cushioning doesn’t matter, but there is less of it, does the mileage matter?

I will check the bounce later, but most likely I will take the shoes out to a thousand miles.

Brad, New York: After years of running w/o serious injury I took a long run in the rain in my oldest shoes, which got soaked. My left knee bothered me the next half decade. Although I am relatively light I now replace my shoes every 300-350 miles. I appreciate the point of this article that this is a personal preference matter. However, one scientific point is missed in this article. My friend, an executive in a company that provides the raw materials for soles insisted that they were only designed to last 300-500 miles. The material even degraded after 4, 5 years on the shelf! Running shoes were a small part of their biz, so he wasn’t motivated by shoe sales.

AceK, Oakland: The idea that there is one standard distance for replacement is ridiculous. As others have noted, it depends on the shoe, the runner, and the surface. I can feel when it’s time for new ones. That’s typically over 500 miles on trail shoes and 200 or less on racing flats.

Susan, Canberra, Australia: One of the great advantages of running barefoot is that you don’t have to worry about this vexing issue. Now that my achilles tendons are working properly, I feel I have more bounce in my stride barefoot than I used to have in a brand new pair of runners.

Suzanna, Dallas: I had an aerobics teacher whose rule of thumb was: if your knees hurt, it’s time to replace.

Will Nemirow, Denver: no evidence supports any correlation between running shoes and injuries in general..

Brad, Cold Spring Harbor: i have been running daily (about 360 days/year) for 30 years (i’m 48). When i started running i was logging 60 miles/week. I got shin splints a few times, and noticed that I could prevent them by changing shoes about every 250 miles. Nowadays i run only about 30 miles/week, but I still change my shoes after 250 miles. I haven’t sustained an overuse injury in the last 25 years.

Richard, Bozeman, MT: Many of us are minimalist shoe runners. (Works great for me, but it’s not for obstinate rear foot strikers) For our group I think this may be a non-issue. I have gone through about 7 pairs. I have a five finger shoe that wore out on top, so I threw it away. I had another that got so thin on the bottom that it started to hurt on gravel. Threw those away. Some pairs just sit in my closet because I liked the newer models more. For those of you who like to run with little mattresses attached to your feet, toss them when your biomechanics starts to deteriorate. See you on the trails!

Cheryl, Westchester Cty: Corollary question: are newer designs so much better than old ones? Are the super-expensive running shoes measurably better than mid priced and low priced ones? There’s a lot of hype – but? Seeing a lot of manufacturers jumping on the minimal craze and changing their lines — suggests that there’s a big style thing going on here, too.

House Wulf, Richland, WA: I run in Merrill minimalist shoes in the winter and Teva sandals when it is warm. And long before that New Balance tennis shoes. These sandals and minimalist shoes taught me that cushioning is not an important issue though running geometry is important (read ball strike). So, do not let crushing of the padding be an important criterium. Toss when wear causes a bad wear pattern that results in bad strike geometry or you just hate them because they stink. or because they look bad. Try to get 2 years out of them.

Jean, Virginia: When I complained to my fencing coach that my ankles felt gimpy (I also run), he said you need new shoes and arch support. The arch support more than new shoes made the difference. Make sure your shoes have adequate arch support; replace the manufacturer’s insets if necessary with something stronger. It turned things around for me.

JW, New Mexico: If you run with multiple pairs of the same shoe you’ll know when it’s time to retire a pair…they just don’t have that “bounce”, “spring” or “boing” like they used to have.

Aaron, NYC: How about we walkers, i walk 35 miles a week and i have no idea how often i should buy new shoes ?????????????

Heron, Chicago: I start wearing out the outsole before the cushioning starts to go.

Leah, Colorado: I’m definitely the kind of person who will stretch anything beyond manufacterer recommendations (toothbrushes, oil changes, contact lenses) but I have found that in 14 years of running ~20 miles per week (so not huge distances but consistent), I eventually start to get plagued by minor aches and pains that miraculously disappear when I replace my shoes. I don’t keep track of how long I’ve had my shoes or how many miles I’ve run in them but as soon as I find myself stretching my IT bands at work, I know it’s time to get new shoes and the problem goes away.

Amy, Iowa: Yeah, great topic. I order new shoes when my ankles start to hurt. I’m mostly a treadmill runner now, but on this regime, I haven’t had a layoff from injury in…uh, I can’t remember the last injury. I just wish New Balance would quit changing the numbers on the $%!$@ shoes.

When Do You Replace Your Running Shoes? – Part A

How often should we replace our running shoes? Worn out shoes increase the risk of injury. While most running shoes will last for  300-500 miles, each runner should make their own assessment as to whether they should keep or replace their shoes. Stability, cushioning, and shock absorption, as well as they way our foot strikes the ground, will determine our decision.

We asked several runners, when they would retire a running shoe, and here are their responses:

Aaron Burke of the minO, Massachusetts: The minO shoe wear sensor automatically tracks the use of your running shoe and shows you when to replace them based on the suggested life of the shoe. I suffered a stress fracture from outrunning my shoes 3 years ago while training for the Lowell 1/2 marathon. To track the use of my shoe, I invented the minO which goes under your sock liner and counts the number of times and the intensity you strike on the shoe. A progressive set of lights show you how close you are to the recommended end-of-life for your shoe. It is like a toothbrush’s blue wear strip for your running shoe.

Check it out and let me know if the minO can make sure you Don’t Outrun Your Shoes! http://www.runmino.com/buying-your-mino/


Corey W., Vancouver, BC, Canada: I run with New Balance shoes, I find them to be the best quality and performance. I am a fairly moderate runner, and range from trail to city running. Generally when I’m in store the staff recommends me to upgrade my shoe every 6 to 12 months (it depends upon the shoe, your weight and the surface you’re running on).

Surprisingly with the New Balance Minimus ( http://www.newbalancevancouver.ca/minimus-10-trail-running.html ) and the ( http://www.newbalancevancouver.ca/1080.html ) 1080 being completely different shoes with different levels of cushioning, you would think that the less cushioned shoe would wear out faster, but because your foot strikes the ground at a different place the shoes have a very similar longevity.

Dr. DA, New York: I use my sneakers until I notice the sole is wearing down, and thus the cushion is lost. Loss of cushioning leads to increased direct impact/shock on the foot, especially the heels which can cause an injury like heel spurs.

Suzanne, Edinboro, PA: I know what happens when they wear unevenly, as everyone’s do, you get tendonitis like I did. When the heels are uneven get rid of them!

Smithaca, Ithaca: My suggestion: replace the shoes as soon as you find one with “Made in the USA” on the box or label.

Fred, Setauket NY: I retire my shoes when my toes come through the tops, and the lining on the heel erodes away. Takes about 600 miles/6 months.

Dr. J, Gainesville, Fl: I’ve run over 100,000 miles. I replace my shoes when they get holes in the body of the shoe.

Bev, New York: I walk..and wearing different shoes affects different areas of my body – it’s not so much about the feet as it is the knee, hip. I have some shoes that cause no knee or hip or foot problems. Other shoes, some proper running shoes make one knee, or the other…or sometimes the lower back hurt. So for me it’s not about the feet.

Tyler, Chicago: I walked all the way across the United States in 2011. Over 3200 miles, I went about 1000 miles in a single pair of sandals. I ran about 500 miles of the trip. I think running shoes are overrated.

Matt, NY, NY: I use them until they either have no more traction or they fall apart.

Nate, Brooklyn: The article title is misleading. “When to Retire a Running Shoe” makes the reader expect a clear answer. Instead, the author concludes “no one really knows.” What a let down.

Dave, NJ: Some people may have a thicker natural amount of padding on the soles of their feet making them less vulnerable to injury and trauma therefore could wear worn shoes safely. I would guess most heavy users pull the trigger too quick and change shoes frequently.

Takis, NJ: I write in pen on the heel the date of first use…then I go ~ 200 -250 miles from there

Tinah, Idaho: Ask Nate Silver!

Paul Kramer, Poconos: In the early ’80’s I weighed 160 lbs. and ran 25 miles a week and 10K’s in under 40 minutes. I could almost instantly tell when my one of my dozens of pairs of Nike Internationalist no longer had bounce or cushion; i.e., it seemed to be a black/white thing as opposed to gradual. Now I’m 200 lbs., exercise every day but only jog (shuffle?) once or twice a week. My 5K’s take over 30 minutes. I no longer have a “feel” for when a shoe is worn and hence have three or four pairs (I’m wealthier) of Asics lying around which I pick at random. I’ve come to no conclusions though these observation may feed the survey folk. Replies from other runners requested.

Catherine, Mission Viejo: Runners get injuried because they don’t have a leg strengthening and stretching routine. They also fail to eat properly. Running is a sport. Like any sport, the body must be conditioned, trained, and properly feed. Most people just want to run. When I talk to people about conditioning they always say they don’t have the time. Then they tell me about their injuries.

Danielle, Chicago: I think it’s personal. I use lightweight shoes and I got injured (IT band problems,  ankle issues) with each pair of shoes that went over 250 miles, so that’s when I change them now (and I’ve been injury-free for a while now!). I think most runners who have been at it awhile have a sense of when they need to change shoes – they don’t really need a study to tell them.

David Holzman, Lexington Massachusetts: I ran a pair of New Balance from around 1998 to 2008, probably around 7,000 miles. My weight probably averaged in the high 140s during that time.

Sal, Rural Northern CA: My ex-partner was a runner and we had the same shoe size. I am not a runner, but I always had nice “new” running shoes to kick around in as they were replaced for new ones.

Just to add to the info here, she replaced them when she began to sense minor aches and pains in hips or knees.

George Dyck, Arizona: After 40 years of running about 600 miles a year I have settled on replacing my shoes every year on November 1, even when my wife objects to my extravagance! At age 75 I have never had the experience of being laid up by foot, knee or hip injury. The key is the footfall, and that is why running on dirt is not the best. You need an even surface so that the force of every footfall can be measured and controlled.

Pooja, Skillman: George, I salute you on your success and longevity in your running career! Unfortunately for me, injuries forced me to retire from running and now I walk regularly for exercise. You have found the key to keeping yourself running and injury-free. I guess it is a personal thing for every runner, and he/she needs to learn when it is time to change their shoes.

Morningsider, NYC: When is it time to retire a running shoe? Right before you take it out of the box.

Gus, Arizona: When you see a really great new pair of shoes then it’s time to replace the old ones. That should be often enough for a normal person.

Deranieri, San Diego: After a year. Unless I run the Camp Pendleton Mud Run before the year is up. In which case I pitch them as soon as I complete the run.

Wayne, Brooklyn: What is this ‘bounce’, ‘spring’ and ‘boing’ you all speak of? 155 pounds of flesh hitting into pavement never feels like any of that and I’m ‘light footed. I run about 30-40+ miles a week now, increasing gradually over the last two years. I wear light shoes as well. New Balance MR 1400’s and love them. I am a fore foot striker after months of injury with mid-foot and heal to toe I then trained to run fore foot and haven’t looked back.

I feel like the shoe does little to prevent or cause injury. Lacing has defiantely impacted my performance and led to injury, so I guess the shoe design could contribute to injury, but the age, I’m skeptical.

I’m at 600+ miles now on this pair, I run trails sometimes, but usually asphalt. I’ve noticed that more often than not any personal injury comes out of bad form coupled with overtraining and or lack of rest. My worst injury was from bad lacing and bad form and too many miles.

Would love to participate in a study and see some real scientific study come to fruition here. Hopefully, not funded by shoe companies.

GeriMD, California: What about when to retire shoes used solely (sorry) for low-impact cardio? I have a pair that I use exclusively at the gym, so, they look like they are in good shape. Is there a limit to their lifespan?

Clara, Third Rock:  Retire them when the grip is gone and they’ve become slippery.

IggyDalrymple, Arkansas: I say retire them before running. I prefer barefoot.

Jaque, Champaign, Illinois: My shoes never, never wear out on the bottoms. Which means, they start fraying on the top. I continue to use them as long as I can keep my foot inside! I have frayed shoes that show most of my socks but have no impact on running on trails. Don’t waste money (and environment), keep using your shoes as long as you can keep your feet inside!

Ryan, Tucson, AZ: As for me, I my practice has been to keep track of the miles I run with each pair and replace them after 300 miles.

David Smith, Colchester, Essex, UK: When you can jump higher in your new shoes.

Claire, Brooklyn, NY 19: I keep track of the mileage on my shoes, and retire them at about 500 miles; however I also replace the insole about halfway through. Seems to work OK. My only complaint is that the shoe companies keep changing their models so often, I would rather stay with a design I like forever instead of having to figure it out all over again every couple of years.

Review of Saucony Triumph ISO Running Shoe

Triumph ISO Saucony
Running is a good physical activity that improves cardiovascular fitness, strengthens your bones and helps you maintain a healthy weight. It is important to have best-fitting running shoes to lessen the chances of injury (i.e shinsplints, plantar fasciitis, tendonitis, etc) . For me, the best pair of running shoes are those that just “disappear” from my feet when I run.

The Saucony Triumph ISO is the latest version of the Triumph line. These shoes are the Editor’s Choice for Runner’s World in March 2015. The Saucony Triumph ISO is the eleventh iteration of Saucony’s Triumph line. Saucony has not used a number for its new line but instead replaced it with ISO which stands for ISOFit. The ISOFit has taken a few grams of weight off the upper of the shoe. The next improvement is the PowerGrid for which Saucony’s shoe-lab has added more cushioning than Triumph 17. This allows more free movement for the foot.

I have bein using the Saucony Triumph ISO for long runs. I find them comfortable for my daily runs.

The following pros and cons can be noted about Saucony Triumph ISO


  • Delivers a richly cushioned running experience, and therefore it’s especially suitable for long runs
  • Provides a soothing feeling through the entire gait cycle
  • The inner sleeve is very soft, made from air mesh that is stretchable
  • ISOFIT fits closely to the feet giving a sock-like feeling
  • Available in various colors
  • Suitable for neutral foot motion– The PowerGrid plus sole is extremely light. The shoe weighs 255g only!


  • Price tag is on the higher side ($150) but is worth buying for high mileage runners
  • For speed work the cushioning is excessive

What others are saying about Saucony Triumph ISO

Review by Dave
I run around 20-30 miles/week and have used most of the top brands. I love the Saucony Triumph ISO shoe as it cushions like socks and the stack height is perfect for my long mile running.

Review by Kim
Saucony suggest to buy one size up as the shoes run smaller, but for me it was opposite. The shoes are the shoes are wider and larger as the ISO fit is very flexible and I have to tight up the laces firmly to get a good fit. The shoes are very lightweight and comfortable. I found them suitable for running, but for walking I felt something is wrong but my guess I need a lower size maybe will correct my walking experience with them.

Saucony Triumph ISO shoes are perfect for runners seeking a neutral shoe with an incredibly plush ride. The Triumph ISO provides the right cushioning and gives a good springing off the ground feel.

The Adidas Trasher – A Shoe Worth Buying

The Adidas Trasher is a trail running shoe that provides comfort and stability. If you run in city terrain, it might not be the best choice but if you are a trail runner you will get value for money.

Running is just one of many ways to stay fit and healthy. However, if you do it wrong, your health will be in danger. Especially knee injuries are common among runners. Therefore, it is important that you run on the right ground, wearing accurate shoes.

The Adidas Performance Men’s Thrasher 1.1 M Trail Running Shoe is such a good option. Many athletes use it in order to avoid injuries and to have a comfortable feeling during their everyday exercise. (more…)

How the Air Jordan Shoes Empire Was Built

The Nike Air Jordan collection is one of the most famous shoe and apparel collections in the world for Nike, and its numbers hold that to be true to competitors such as Adidas and Puma. It is a billion dollar empire now for Nike and its leading man, Michael Jordan. The NBA legend pulls in hundreds of millions on income just from the Air Jordan line alone. It’s hard to believe that in the beginning of his career, he nearly turned it down and would have let it all go out there door without giving the brand any chance. Michael wasn’t interested in a working partnership with Nike and he himself was still a rookie in the NBA, playing for the Chicago Bulls. (more…)
