On a Shoestring outfits runners in shoes, apparel, and gear to keep motoring humans moving in comfort and style. The store's staff of running enthusiasts, including many certified running coaches, matches customers with their predestined pairs using precise shoe fittings, arch-mapping wet tests, and treadmill-gait analysis. Finish-line seekers can choose from the store's bevy of brand-name jogging clogs, such as a pair of Brooks Adrenaline running shoes ($100 for both men's and women's styles) or New Balance 927 walking shoes ($114.99 for men and women). DownUnders orthotic footbeds ($37.99) add comfort and can help tame freewheeling ankles. For those who amble sans socks, Orthaheel orthotic sandals ($54.99) cradle sleepy dogs in specially shaped footbeds. Protect vulnerable shoe cargo in an array of apparel, including the Brooks EZ T athletic shirt ($28 for both men and women), which shields torsos from the elements without impeding motion. A Bodyglide antichafing stick ($5.99) draws a dividing line between close-quartered body parts, preventing them from irritating each other and providing years of anecdotes for when they someday get along. Other available accessories include sunglasses, watches, hydration systems, and nutrition supplements.
