Every Altra shoe is built on a Balanced Cushioning™ platform that positions the heel and forefoot an equal distance from the ground. This natural foundation aids in optimal alignment, cultivates better form, and encourages a low-impact landing. The FootShape™ toe box allows the toes to relax and spread out naturally and the big toe to remain in a straight position for maximum stability and power. Altra shoes feature a Fit4Her™ technology that caters to the specific form of the female foot, which has a narrower heel and midfoot, a higher instep, a longer arch, and unique metatarsal spacing.
