This style is full-grain leather with a soft mesh lining inside and features the DurangoA(R) X-Pand System(TM)-a hidden gore expansion for a universal fit and easy on/off. It also has a comfortable 7-layer comfort system and a classic square toe design. The first layer is the DurangoA(R) X-Treme Comfort Footbed(TM) with memory foam for all-day comfort and support. The second layer is an EVA cushion layer that contours and molds to your foot. The third layer is a 3/4 genuine GoodyearA(R) 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 3/4 heel tuck. The fifth layer is the patented Dually Shank System(TM), which contains two fiberglass shanks for medial and lateral torsion stability and midfoot support. The littleway stitch binds the outsole, heel tuck, and upper for absolute durability. The sixth layer is the ABS heel base, which is nailed-weight relieved for lightweight durability. The seventh layer is the slip, oil, and abrasion-resisting rubber outsole that offers instant gratification. The 1A 1/2" rocker heel lessens stress by promoting a more natural heel strike, and the rolled shank area is perfect for stirrup-friendly ease. 1 1/2" Rocker heel Patented Fiberglass Dually Shank System(TM) for torsion stability and mid-foot support Rolled shank area Genuine leather welt with double row cotton stitch Slip, oil and abrasion resisting rubber outsole 3/4 genuine GoodyearA(R) welt construction Littleway shank stitch for ultimate durability Cushion flex insole with rigid rear foot stabilizer Square toe Full-grain leather Durable and rigid nailed ABS heel Soft mesh lining
