The La Sportiva Bushido II mountain running shoes have all the qualities necessary for use in skyrunning competitions, namely excellent grip, optimal lightness, and good technicality. They guarantee stability on all terrains. The La Sportiva Bushido II features the STB Control construction with the TPU skeleton implanted on the side of the upper and joined at the bottom to cover the sole in the middle. This technology provides optimal foot wrapping and stability. It also reduces the weight of the shoe. The slip-on upper construction covers the foot like a pair of tights without compressing it or exerting pressure. The Bushido II has been specially developed to allow runners to run safely on all terrains. The FriXion Red bi-mesh sole is made up of an inter-sole that forms a progressive angle of support on the ground and improves stability. To increase its durability, a thermoplastic film has been added to the reinforcements to prevent damage from friction and abrasion.
