Full-Grain Leather Upper To ensure its quality, we put our leather through six different tests before making our selection. Our full-grain leathers are the strongest and most durable form of leather. Danner Dry 100% waterproof barrier allows moisture to escape without letting water in, keeping your feet dry and comfortable all day long. Removable OrthoLite Footbed Three layers of varying density are combined for maximum cushioning and support. The entire footbed is made of open-cell polyurethane for better heat dissipation and air circulation. Vibram® SPE Midsole This rubberized EVA midsole maintains the same cushioning properties as traditional EVA, but is more durable and won’t break down as easily. This technology enhances rebound, comfort and support. Vibram® Fuga Outsole With its self-adapting lugs and specially formulated Megagrip compound, this outsole provides incredible grip on both wet and dry surfaces. How It Fits Designed for versatility, the DPDX has a low profile for everyday wear. Whether on the trail or urban exploring, this last was built to offer enough room for comfort while maintaining a sleek profile. Ortholite footbed included. Please note that if you are in-between sizes, we recommend sizing down a half size for best fit.
