Designed for rolling and steep terrain, the MSR Lightning Ascent 25 Snowshoes are ultralight thanks to vertical frames (versus tubular). Aggressive traction teeth penetrate off-piste crust and Televator;heel lifters make climbing easier to reduce fatigue. Step-on bindings fit a variety of boots and are fast, secure, and easy to use. Total Traction aerospace aluminum frame provides not only structure, but also unprecedented 360° traction. Raised rear frame allows for a more natural stride while reducing heel drag and minimizing fatigue. True Hinge steel crampon enhances foot stability and minimizes heel drift, resulting in a more efficient and natural gait. Televator heel lifter reduces calf fatigue, making climbing easier and more efficient. 100% waterproof materials won't soak up water and freeze; straps remain easy to use in all conditions. Lightest snowshoe in the category.
