Runner’s feet are a funny and fickle thing. What works for one person does not necessarily work for the other, even if two people have a similar foot style. Sometimes finding the perfectly designed shoe for your pronation, supination, flat foot, or high arch still isn’t enough to provide you with the proper support needed to withstand the pounding of mile after mile on the pavement or trail. This is where aftermarket inserts and orthotics come into play. Tuli’s (a member of the Medi-Dyne umbrella of companies) has a product that just might pair well with your favorite pair of kicks to provide the perfect amount of arch support and heel cushioning you need.
