Get a precise fit and luxurious cushion in the La Sportiva Jackal II BOA. The compression molded EVA midsole foam with Infinitoo™ PU inserts gives you a combination of cushion and stability, so you can spend all day on the trail. La Sportiva refreshed the upper to make it lighter, more breathable and more eco-friendly, and they added a new heel and tongue construction for a better fit. The BOA® lacing system gives you quick-fit laces for a precise feel. The BOA version has a tighter, more race day ready fit and a higher collar for more ankle protection than the La Sportiva Jackal II. The Frixion® XT 2.0 Rubber Compound and 3.5 mm lugs provide both traction and durability for you to tackle technical trails with ease. Whether you enjoy a hike with your dog or run ultramarathons, the La Sportiva Jackal II BOA is a great choice for cushion and traction.
