does your physio work for nike...un'f***ing'believable...nike would having you change every 1000-200 miles if they could get away with it...changing shoes every 300-500 miles is f***ing ridicilous...remember kenyans run in bare feet...i would say never change shoues unless they are worn out, torn or broken...otherwise wear them you f***ing jackass
hey asshole, stop running on concrete and yuor knees will stop hurting...holy shit are you f***ing dumb.
I went to a physio and he told me 300 miles last year. I had 400 miles on my shoes at that time and got a kneecap pain injury after 400. I am now on about 270 on my current shoes and i got the same knee injury last week. He now told me 250 miles and i should change them. Is this correct??? I'm not sure if there's a link between the vmo?kneecap pain and the wearing of my shoes, but it could be. How many miles do you put on your shoes, and what do the elites do. PS-I wear custom made orthotics.
I would say that 300 is low. Here are some factors that change the life span of your shoes... I'm sure other people on this board can add some more (or disagree with me).
Surface that you're running
The way you plant your foot. If you wear your soles away at an angle so that your shoe leans severely to the left or right it is time to change shoes because it lends to improper joint alignment each time you land.
Your weight.
The shoe itself.
If you also use them as walking shoes.
If you don't take care of them (ie putting them in the dryer)
Lifting heavy weights in them wears out the cushioning quicker.
Anyone think of anything else? Are you sure you need orthotics? I only ask because I think that some people who need orthotics for dress shoes don't need them for their running shoes assuming that they buy the proper style shoe. Good luck.
about 500 miles for me.
about 4-500 miles, but 2 pairs of trainers alternating so takes twice as long to get there.
Replace them every 500 miles or so is the popular guideline. If you run high mileage and do that, Nike thanks you.
I've noticed that 500 is very conservative. I don't replace them until the shoes begin falling apart. There is still plenty of cushion left in a shoe after 500 miles-not that your body needs it, unless you are on the heavy side.
no, light enough (62 kilos and 5ft, 10inches). The physio i went to said my right foot was a lot flatter than my left, and therefore my stride is badly pronated, so that's why i got orthotics.
Uh, I change them after every run.
Between 400-500 miles. I usually tell. Little aches and pains start to flare up when I need new shoes.
Schoolsy
no, he doesn't wotk for nike, but it's just that it's kinda coincidental that this knee pain has reared it's ugly head when my shoes were up to 300 miles twice, once now and once about 6 months ago. Oh, and i only wear them for running. But you're right, i thought 250 m iles was a bit small, because that's only 5 weeks for me.
It sounds like you need to evaluate your biomechanics while running. Shoes are only able to provide minimal shock absorbsion and very little stabilization. After each mile you put on them they began to become less effective at doing both of those objectives. As a result if you have poor biomechanics while running after 300mile your body is not getting the optimal balance of cushioning and stabilzation needed for impact on each stride. Good luck!
i usually get to 700. i'm a cheap bastard. also, once i get to the point where they don't feel as good, i only do short runs in them and use newer shoes for long runs and hard days.
I change my shoes every 500 miles, my underwear every month, and my socks every week.
