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