Salomon designed the Men's S Lab Sense 4 Ultra Trail Running Shoe for long distances in dry and hot conditions. SensiFit and EndoFit uppers wrap breathable mesh around your forefoot and sides for improved feedback, precision, and snug fit. Salomon's speedy QuickLace closure also secures the upper's fit with a quick and easy Kevlar drawcord, and there's a pocket to keep the drawcord in place while you run. The S Lab Sense 4 Ultra Trail Running Shoe also features Salomon's Pro PrioTection midsole for natural motion over rugged terrain. This midsole has a ProFeel Film for an enhanced feel, an OS Tendon for stability, and three layers of EVA for moderate to heavy cush. The shoe's sole has Salomon's sticky ContaGrip rubber molded for Dynamic Traction over all sorts of trails.
