spire is an innovative shoe designed for fast hiking. it integrates cutting-edge solutions from la sportiva’s mountain heritage, merging technologies and concepts from both the mountain running and mountain categories. this results in a versatile, waterproof shoe that offers 360° breathability, thanks to the revolutionary gore-tex surround® technology. this unique membrane ensures 360° breathability through an extensive aeration surface that includes the uppers, footbed, and eva midsole, featuring side ventilation outlets made from tpu. the visible aeration channels along the midsole's profile are safeguarded by a robust nylon mono net, stopping stones and other debris from clogging the vents. the mid-cut uppers utilize the nano-cells 2.0™ structure with super breathable cells that collaborate with the gore-tex surround® membrane for extraordinary breathability. the lower part of the shoe features the stability control system™, which integrates the ventilation outlets with the gore-tex surround® technology. the vibram xs trek outsole delivers exceptional grip on various terrains, whether hard, soft, or muddy. you can count on all-around breathability and comfort.

the synthesis of the best technologies for hikers is perfected by integrating the unique gore-tex® surround™ technology, ensuring unprecedented waterproofing and breathability. for the first time, the breathable surface extends underneath the foot, delivering 360° breathability. a special breathable and waterproof layer beneath the footbed allows for lateral moisture exit, keeping your feet dry and comfortable under any circumstance.
