I had this conversation with a client today and I want to emphasize that it’s important to check the mileage of your sneakers. We all love our sneaks, especially since they are so fashionable and comfy these days. But since how long are they giving you that comfy feeling? A safe rule is that good sneakers usually last around 300- 500 miles. If they are worn out, and most sneakers are after 500 miles, you need to trash them. I know it can be difficult to track the mileage and a good rule of thumb is that sneakers should be replaced every six months, which equals around 30 minutes of walking a day. But if you are walking around 60 minutes a day think about replacing them even earlier. Sneakers are aging because they are glued together, and the glue is drying out depending on the age of the shoe, your mileage, weight and time frame of use. That means if you overextend them, you don’t get the same support and might end up with plantar fasciitis, shin splits or other injuries. A good test to check if your shoe is still in good shape is the twist test. Take hold of the shoe at each end and twist it. It should feel nice and firm, if it doesn’t, it’s time to get new ones. I know it can be expensive, but it’s so worth it!
