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. We know you are going to love our new Sawtooth X Mid Waterproof. We've taken our adored original Sawtooth and given it a new grippier outsole, a new Adaptive Cushioning Technology midsole for a smooth ride, and updated its styling for a boot that takes things up to the �_ox�__ degree.
