SCARPA Spin Infinity is a trail running shoe designed for long distances: perfect for Ultra Trail training and off-road competitions. Studied in detail, you will have an extremely comfortable shoe that wraps the foot perfectly without creating compression points that can become painful in the long run. The upper is light in mesh but there is no lack of reinforcements that in addition to avoiding the twisting of the foot inside, prolong the life of the shoe. The midsole instead is in double density EVA foam depending on the support area so as to have excellent cushioning both in the heel and in the forefoot. The whole, then, is completed by a Vibram tread which gives excellent grip on all terrains. SCARPA Spin Infinity trail running shoes
