The basis of the shoe is the Vibram Dynamis sole, which significantly reduces the overall weight of the shoe. This is combined with a double-density midsole for cushioning on uneven terrain. The upper of the shoe is made of thermoembossed suede, lined with a waterproof and durable Gore-Tex membrane. The side rim protects the upper from abrasions and scratches and the rubber tip offers grip and protection. The design from the lace to the tip in combination with a flexible tongue ensures the best possible fit.
