The Altra Olympus 275 HiLo is a max-cushioned, zero-drop trail shoe built for rugged, technical terrain and ultra-distance days. Its latest Altra EGO MAX midsole is 15% lighter and 10% softer than the previous version, delivering a deep, plush underfoot feel over a 33mm stack. A Vibram Megagrip outsole with TractionLug provides confident grip and stability across wet or dry ground, while the one-piece MATRYX woven upper, blending Kevlar and high-strength polyamide, resists abrasion on rocky trails and adds a scree sleeve to keep out grit. The Original FootShape gives Altra's widest toe box for natural toe splay. Best for runners who want a durable, comfortable rig for long trail training, ultra racing, or hiking and mountain traverses.
