It has the Durango X-Pand System which is a hidden gore expansion on the inside medial seam for a universal fit and easy on/off and the Durango X-Treme Comfort footed with Memory Foam for all day comfort and support. It also has a high abrasion heel counter, fiberglass shank for lightweight stability and a dual-density midsole with firmer shock absorbing heel for added stability and a soft shock absorbing forepart for ultimate flexibility and comfort. The rolled shank area and anti-torsion ridged external shank provides added lateral stability and the outsole is a multi-durometer rubber with high abrasion outer lugs for high impact durability and softer durometer mid lugs for added flexibility and increased heat, slip and oil resistance.
