Waterproof winter running shoe designed for training and daily use during the winter months, with an eye towards skyraces in the spring. Versatile, lightweight, and quick to put on thanks to its sock-like construction, it is the perfect shoe for running on various off-road surfaces, featuring a sole that can be equipped with AT Grip spikes. The grippy sole excels on slippery surfaces, and the pronounced shoe lugs maintain grip even on soft or icy ground, enhanced by the optional addition of AT Grip spikes. The fast and intuitive lacing system with a hidden lace pocket, combined with the sock-like collar and a functional, comfortable gaiter, fully envelops the foot without leaving any gaps: this completely prevents the entry of stones, mud, or snow. The lacing system is integrated with the inner shaft construction, providing optimal volume regulation and a perfect fit for stable running, even on traverses. The seamless exterior and the super flexible, waterproof, and breathable Gore-Tex membrane make the Tempesta the perfect footwear for athletic preparation during the winter months.
