La Sportiva Jackal II GTX Trail Running Shoe designed for long distances allow our feet to feel comfortable from the first to the last mile. Upgraded upper including lighter tongue, new heel design mesh inserts and improved lacing structure reduces the number of grams while providing maximum comfort thanks to the fit which adapts better to long-lasting waves and allows more mountain breezes to pass through. Whatever the weather, the GORE-TEX lining keeps our feet dry not allowing water to penetrate inside and allowing its own vapors to evaporate. When we walk lightweight foam softens the ground forefoot and heel inserts stabilize our impacts and takeoffs and a full-length rock guard and TPU toe cap protect soles and toes from bruising.
