The first Altra inspired by and designed with an athlete: Discover the Paradigm 6, a shoe that blurs the line between support shoe and everyday trainer. Elite athlete and two-time Olympian Kara Goucher helped Altra take this shoe to the next level. With her input, they incorporated the Altra EGO MAX midsole, scaling down the overall design while maintaining key support featues.FootShape Toe BoxTraditional running shoes have pointed toe boxes that push the toes out of their natural position – an increased risk for bunions, hammertoes and plantar fasciitis. With Altra’s FootShape toe box, toes can relax and spread naturally and the big toe stays in a straight position. This reduces overpronation, increases stability and provides a powerful propulsion to maximize running performance.Balanced Cushioning PlatformPlaces your heel and forefoot at the same distance from the ground to ensure proper and gentle posture during your trail run.GuideRail A feature found on Altra’s Dynamic Support Shoes that works like a road guide rail, providing guidance assistance only when you need it.Altra EGODual-nature midsole compound with a responsive yet soft feel for increased energy return.
