The Altra Olympus 6 Trail Running Shoe and our hydration vest go hand in hand on our long training days. A generous stack of light EVA foam keeps our soles happy throughout our double-digit miles and along rocky terrain, while the sticky Vibram Megagrip rubber with an updated lug pattern secures our strikes atop dry and wet terrain alike. When we reach the less-traveled singletrack, the upper's reinforced engineered mesh brushes off overgrowth, and its toe cap armors our toes against leaf-buried rocks.
