The Salomon S-Lab Sense 4 Ultra Trail Running Shoe combines a raft of new features designed to improve performance and durability. A lower heel drop supports a midfoot or forefoot-oriented strike, enabling muscles to absorb more of the shock than your joints, ultimately improving balance and overall running efficiency. An Endofit™ upper creates a smooth surface that wraps the wearer’s foot, offering support and comfort during long runs. Located on the upper, a Profeel Film offers protection for trail running in a lightweight and flexible package.
