Over half the injuries runners and walkers experience can be directly attributed to 'worn out shoes.' Worn out refers to the midsole (engine) of the shoe, which is the most important component of an athletic shoe. Don't use the outsole/tread wear as a way of determing how much life is left in your shoes! This midsole component generally lasts about 375-450 miles of athletic use. Cut that mileage rating in half if you additionally use your shoes for anything other than your running or walking exercise (i.e. 'wearing around'). Here is a sample mileage chart to determine how often you might need to replace your athletic shoes.
Exercise Miles/Week --------- When to Replace Shoes
05 Miles/week ----------------- every 18 months to 2 years
10 Miles/week ----------------- every 10 months to a year
15 Miles/week ----------------- every 6 to 9 months
20 Miles/week ----------------- every 5 to 7 months
25 Miles/week ----------------- every 4 to 6 months
30 Miles/week ----------------- every 3 to 4 months
35 Miles/week ----------------- every 3 months
40 Miles/week ----------------- every 10 weeks to 3 months
50 Miles/week ----------------- every 8 to 10 weeks
