Altra Timp 4 Shoes Black The Altra Timp 4 with MaxTrac outsole and multi-directional lug pattern for grippy traction on any trail. Updated collar construction for a smoother, quality fit. Altra EGO MAX midsole with mesh overlay. FootShape toe box Traditional running shoes have toe boxes that push the toes out of their natural position, increasing the risk of bunions, hammertoes, and plantar fasciitis. With Altra's FootShape toe box, the toes can relax and spread naturally and the big toe remains in a straight position. This reduces overpronation, increases stability and provides a powerful boost to maximize running performance. Balanced damping platform Position your heel and forefoot the same distance from the ground to ensure a smooth, correct stance during your trail run. Maxtrac A perfect combination of grip, traction and durability that will "eat" the terrain like a gnarly boss. Other EGO Dual natural compound in the midsole with a responsive yet soft feel for increased energy return.
