The Sawtooth X Low Waterproof Shoe is an updated version of a loved original that lends even greater support and balance. This comes from two places: an updated midsole that uses adaptive foam and a nylon shank to better steady our every step with utmost comfort and a sticky True Tread outsole that clutches the ground with a rubber-to-tarmac-like grip. What remains is the B-Dry membrane for breathability always and protection when strolling through puddle-ridden trails.
