Dynafit Speed MTN GTX trail running shoe is a waterproof shoe for fast adventures on alpine terrain. The waterproof Speed MTN GTX is a lightweight, durable, comfortable running shoe for fast mountain adventures including via ferratas and scrambling. The versatile shoe with its Pomoca outsole features a balanced blend of grip and traction that offers perfect hold on both rocky and soft surfaces. At the same time, the midsole encourages a dynamic running gait while still remaining stiff enough for climbing, for example to gain toe holds on small edges. A Gore-Tex membrane ensures feet stay durably dry even in rain showers and on muddy terrain. The Quick Lacing System is exacting and uncomplicated to save you time. The Invisible Lacing System’s protective stretch lace cover keeps small stones and dirt from getting into your shoe. An additional feature of the shoe is its Heel Preloader Technology, a diagonal reinforcement at the heel that improves hold and fit.
