All running shoes come with stock insoles—you can see yours by peeling it out of your shoes—that typically add another millimeter or two of cushioning. But aftermarket insoles give you more options.
The insoles you can buy separately from your shoes give you different attributes than the stock insole. Some shoe inserts are rigid and supportive, and they’re shaped to influence your foot by providing arch support or other structure. Other insoles give you more cushioning in high-impact areas, like your heel and forefoot.
There isn't one best pair of insoles for every runner—it's all about preference. Some runners and walkers will find the standard insoles that come with their shoes deliver the right amount of cushion and support, but others will like the more customizable experience of a third-party insole. Whatever you choose, make sure it's comfortable for you.
Plus, all of these insole let you swap them between your running shoes and your casual shoes for comfort wherever you go.
Whether you're looking for a little extra cushion or more pronounced support, insoles for running shoes work with your sneakers for a more personalized ride.
