It would be pretty tough to run, walk or just get around without shoes. So when they start wearing out, you'd better know when to toss them out . " When I start to feel pain I get new shoes," says football coach Kip Shaw. " When my shoes start to wear they hurt my feet," says Neil Zlokovich who routinely works out.
Dr. Jeff Appleman is a podiatrist who says letting your shoes wear down can mean trouble for your feet. " You can cause real damage to your tendon and muscles is you're wearing a shoe deficient in structure," says Dr. Appleman. Especially athletic shoes need to be replaced frequently. You can loose more 50% of the shock absorbancy in your shoes by if the shoes are worn down. " For my tennis shoes every three to four months I replace them, dress shoes not as much," says cyclist Corrine Meyer.
The lifespan of a shoe, of course, depends of the kind of shoe that it is. A good leather shoe will last the longest several years or more. Then a dressy shoe or sandal are the next group likely to wear down and of course athletic shoes have the shortest life expectancy. Here's a good life expectancy guideline for athletic shoes.
- Hiking, running, tennis and walking shoes need to be replaced every six months if you do the activity 20 miles a week.
- Basketball shoes every 5 to 6 months if you play four hours a week.
- Aerobic shoes every 8 months if you do aerobics 3 times a week.
