Ridge Runner Sports trains its staff of harriers in assessing fellow runners' needs, ensuring precise pairings of quality running shoes, apparel, and accessories. Based on an analysis of their foot structure, gait, and ability to play recorder with their toes, customers slip into shoes designed for normal, flat, or high arches. Pairs of Mizuno Inspire ($99) and Merrell Barefoot Sonic Glove ($124) shoes stabilize and cushion feet and maintain a dashing, only mildly intimidating look. A variety of inserts slide into any shoe, enhancing arch support for aggrieved tootsies. Boasting brands such as Feetures technical running socks ($24.95), Ridge Runner Sports stocks its sock wall with a cornucopia of styles that keep feet dry, compressed, and free of blisters. FuelBelt two-bottle hydration belts ($42.95) strap duos of canteens to sprinter hips, and purified aqua accompanies joggers with CamelBak Groove portable filtration systems ($24.95).
