Your shoes get about 75 - 100 miles. Most runners I know replace every 4 months. It depends on how often you run. I have a pair here that are about a year old because according to my logs, I've only run about 65 miles in them and walked about 30. I'll be getting a new pair soon. - Anika

Thanks Anika. Can you feel it though when they are run down? I have these sneakers I've had for almost a year, but they seem ok. - Shevonne

I've found that you become accustomed to them feeling "ok" until you get a new pair and realize when you wear them the first few times that the previous ones were worn out. - enza (aka iVenus)

Thanks eac! Anika and you have convinced me to get new running shoes. =D - Shevonne

Check your treads especially if you're an overpronater like I am. EAC is right, sometimes it takes getting new shoes to make you realized how worn down your old ones are. - Anika

Though I'm a walker, not a runner, I believe in every 6 months (I'm walking 25km a week) - Rosie Peters

I've heard to get a few pairs and sort of rotate them, but not so they all wear down evenly... more like, you want to have a mix of new-to-old in your rotation so that you aren't grossly thrown off like you would be if you just switched from a single old pair to a single brand new paid. - Andrew C (✓)

Thanks Anika for the information and Shevonne for asking. My running shoes probably have about 300 miles between treadmill and work. - Janet

Anika, that doesn't seem to add up to me. I wouldn't consider someone a "runner" who goes less than a mile on foot every day.... I replace shoes when the heel starts to separate or develops a hole too large to ignore, basically. - Karl Knechtel

Yeah. To be fair, I really don't do much running. But I do a hell of a lot of walking. :) And I like to wear thick socks. :) - Karl Knechtel

also depends on the surface you run on etc. Good rule is about 300-500 miles for a decent pair of running shoes. Use them ( only to run in until they are older - than use them for general use. ( then use them to paint or garden in and then recycle them :) - Tracy Benham
