Combining cushioning and lightweight design, the adidas XCS 3 can soften and speed up your long-distance run. Rubber sharkskin outsole provides nearly perfect grip on uneven surfaces. Featuring an updated longer and lower design, the full-length EVA unit provides a low-to-the-ground feel and exceptional cushioning, creating a ideal ride for middle-to long-distance runners. Working with the stretch tongue, the air mesh upper increases ventilation while providing a gentle, glove-like fit, preventing your feet from slipping and helping you stay comfortable throughout your run. The mono-mesh insert enhances heat exchange between the foot and outside elements, keeping your feet cool in the heat and warm in the cold. The spiked version includes 3/8" pyramid spikes and a wrench. Wt. Spike: 6.2 oz. Spikeless: 6.0 oz.
