The summit of Utah's Mount Olympus is gained via a brutally steep trail that climbs over 4,000 feet in under four miles, so running it will really put the Altra Men's Olympus 2. 0 Trail Running Shoe through its paces. You can be confident it'll crush it, though, because its Zero Drop platform places your heel and forefoot at the same height for a natural stride, while the dual layer EVA foam midsole and energetic A Bound foam reduce impact and increase return energy at each step off. Altra also added a comfy Contour footbed for even more cushioning, because 4,000 feet of rock hopping can take a toll on your arches.The Olympus 2. 0 also features Altra's TrailClaw sole, which utilizes a trail specific Vibram rubber that is mapped to support the bones and tendons in your foot. A FootShape toe box also lets your toes spread out naturally to ensure stability on rugged terrain. On top of all that, Altra equipped the Olympus 1. 0 with a quick drying and durable Trail Mesh upper to ventilate and keep your foot cool, and a Gaiter Trap to accommodate gaiters without having to wrap them around the sole of your shoes.
