The Carbo-Tec LT has the same great performance found in the original Carbo-Tecs but now with a much lighter sole. The thick EVA midsole cushions and acts as a shock absorber with each step. A fiberglass shank is added for arch support and stability. A rubber skin coating finishes the outsole and gives this boot a foundation to withstand the many miles you walk each day.The upper is joined to the outsole through a Goodyear Welt, one of the strongest and most durable bonds in footwear. This Carbo-Tec LT is now lighter than ever and built to last!
