The Twisted X Boots Rancher Cowboy Boot has the SD molded, machine washable memory foam footbed, the very stable XSD insole with built-in composite shank, and rubber outsole. The key difference here is the removal of the midsole for a dressier appearance. It’s lightweight outsole with an EVA midsole that extends into the heel making it super comfortable and light weight. Goodyear stitched through welt.
