Our proprietary insole is what we’re known for. Molded to match the specific shape and construction of every pair we make, this purpose-designed technology delivers the kind of fit, feel and performance that’s unmatched in the industry. A proprietary rubberized EVA that adapts to varying terrain. 100% recycled polyester laces and webbing, and quick drying 100% recycling polyester lining and 50% recycled waterproof lining help us lighten our impact on the planet. Our proprietary Trail Tread outsoles feature more than just a rubber compound. There’s no denying feet sweat and trails can get muddy. There’s also no denying the ability of our proprietary waterproofing system, B-DRY, lets sweat escape while keeping moisture out. The Sawtooth X Low Waterproof is even more capable than our beloved original. It has a new outsole for superior traction and a new Adaptive Cushioning Technology midsole for an even smoother ride. But among all this new-ness it retains the same great fit and feel and our B-DRY waterproof technology, so you can be confident taking on the trail, puddle filled or otherwise.
