How long have you been wearing the same shoes to the gym or to workout? Chances are if you have not changed your shoes within a year, you are way overdue for a new pair. Worn out shoes that are not replaced properly will wreak havoc on your legs and joints. Shoes lose their shock absorption, cushioning and stability over time. Inadequate cushioning and support will set you up to have knee problems, shin splints, or other joint issues in the long run. Also failure to replace your shoes can lead to overuse injuries, so the best thing to do is to replace your shoes when their worn out.
So how often should you replace your shoes? Well the general guideline is approximately 350 to 500 miles. This number is also contingent on body weight, frequency of use, and the surface you workout on. Mark on your calendar when you purchase a new pair of tennis shoes and be cognizant of how often you use them. Pay attention to how you feel in your shoes. For instance, If you feel your shoes are lacking support or your getting shin splints more often, these could be a signs of old shoes. Try twisting the shoe, if it twists really easily that could also be a sign. Finally, do a comparison of your recent shoe to a newer pair. If you think the newer ones offers better support more than likely you need to replace your old shoes.
Now use this knowledge the best way you see fit. The more you know, the better decisions you will make in the long run. Again be wise and toss out those old shoes.
