Ten years ago, the Sawtooth put us on the map in outdoor footwear. The new Sawtooth X retains all the things that made the original so popular with the addition of new aggressive styling and new materials like our Adaptive Cushioning Technology midsole—all you need to map out your next adventure. Featuring a proprietary rubberized EVA that adapts to varying terrain. This unique blend of dualdensity, lightweight cushioning system provides the wearer a high level of energy efficiency and a softer heel strike landing zone.
