How hard is it to buy running shoes? Slightly less hard than buying craft beer is these days, but only slightly. Fortunately, runners have the American College of Sports Medicine to turn to for advice, lots of advice. Look, here’s some now: The college recommends that a running shoe have “minimal heel-to-toe drop: This drop is the difference in the thickness of the heel cushion to the thickness in the forefoot cushion area. Shoes with no drop or a small drop 6mm or less are the best choice for allowing the foot to normally support loading during each gait cycle.” Here’s more: a running shoe should be “neutral, meaning the shoe does not contain motion control or stability components. These extra components interfere with normal foot motion during weight bearing.” And more: a running shoe should be “light in weight (10 ounces or less for a men’s size 9; 8 ounces or less for women’s size 8)”. And more: “Avoid buying shoes based on advice given after someone in a store has watched you walk. Your gait and foot motion are very different when you walk and run.” More advice from the American College of Sports Medicine can be found here.
