New, by popular demand, the Edition leather series combines many of the Treksta technologies and Nestfit anatomical design, into an everyday casual shoe. The edition easily moves from work to dinner, travel to trail. The Edition Zero Tie features a simple self-tying, hands free lacing system. The foot-activated lacing system eliminates the need to bend over to either put on your shoe, or to tighten the laces. A simple backward motion of your foot tightens the lace to your desired tension, and a slight tap on the release pin opens the shoe for easy in and out movement of your foot from the shoe. One word "amazing". Two words "amazingly simple". NestFIT system cradles your feet, accounting for every contour as it follows the natural flow and design of the foot. Upper, insole, midsole, and outsole come together like never before.
