The Brooks PureDrift minimalist running shoe is designed to be like an extension of your body. Sleek, anatomical upper with ultra-breathable mesh and a featherweight feel. Tuned Density midsole better corresponds with gender and weight categories, delivering a custom balance of cushioning that’s not too soft or stiff. Dual toe box split allows the forefoot to flex through its three functional units, engaging the runner's natural balance. Nav Band wraps over the instep to comfortably secure the foot in place. Dynamic stretch provides just the right amount of reinforcement and conforms to individual foot shape and size. Ideal Heel promotes a natural foot strike by landing in a more forward position on the foot. This aligns the runner’s center of gravity and encourages optimal energy return. BioMoGo earth-friendly midsole technology, is blended with Brooks® DNA smart cushioning to create a springy return and custom comfort. Anatomical Last is designed from an anatomical form. The shoe’s shape contours the foot for a glove-like feel and provides support for every part of the foot. Wt. 5.1 oz.
