The Altra Superior 4.5 is a fast and grippy training shoe that features their Quantic™ midsole offers a lightweight yet responsive ride for high-speed trail days. The TheMaxTrac™ outsole and multi-directional lug pattern brings grippy traction to any terrain. Underfoot, the removable StoneGuard™ offers lightweight rock protection for when the trails get extra rugged. Altra styles are built with their FootShape™ design that gives your feet more space to sit naturally. This shoe also has the Altra Balanced Cushioning™ platform which positions your heel and forefoot at an equal distance from the ground, encouraging better alignment, better form, and a low impact landing.
