A new slim profile improves efficiency and eliminates weight, while the hinged ankle cuff, molded heel counter, and stiffer race sole optimizes power transfer. Speed Lock laces, a Thermo fit heel, and a more precise race fit combine for additional support. Inner boot comfort is maintained by a breathable Triple-F membrane that also repels the elements.
Dry, warm & breathable
The Triple-F Membrane keeps water and snow from entering boots while allowing excess heat and moisture vapor to escape. The climate inside the boot stays warm and dry, no matter what the outside climate is.
