This is the men's 12 Belgian Brown/Denim Blue Durango Rebel Pro style. It's full grain leather with a soft mesh lining inside and has the Durango X-Pand System which is a hidden gore expansion for universal fit and easy on off. This style contains a comfortable 7-layer comfort system. The first layer is the Durango Triple X-treme comfort removable polyurethane footbed with memory foam for unparalleled comfort. The second layer is an Eva cushion layer that contours and molds to your foot. The third layer is a ¾ genuine welt construction and a genuine leather welt with double row cotton stitch. The fourth layer is a two-layer innersole with a flexible full-length bottom and stabilizing rigid ¾ heel tuck. The fifth layer is the patented Dually Shank System which contains two fiberglass shanks for medial and lateral torsion stability and midfoot support. The little-way stitch binds the outsole, heel tuck, and upper for absolute durability.
