The Scarpa Rush TRK GORE-TEX boots dial in support and protection in a boot with a suede leather upper and rubber toe cap, backed by GORE-TEX for guaranteed protection against the elements. The upper balances the lightweight, nimble feel of a trail running shoe with the support and protection you expect from a hiking boot. Support, protection and traction underfoot are courtesy of the exclusive PRESA sole with Interactive Kinetic System (IKS) technology. The IKS system features internal shock-absorbing domes placed in key ground contact areas that function as mechanical shock absorbers, while the SuperGum rubber compound provides sure-footed grip on any terrain you encounter. Dynamic Stabilizer Torsion frame supports the arch and wraps the heel on both sides. Ergonomic TPU cuff with grooves of differentiated thickness for anti-torsion control - Medium-density EVA midsole for support and cushioning - Slotted design for cushioning - Rubber outsole developed by Scarpa with high-performance SuperGum high-performance rubber for grip and agility Technology: - GORE- TEX Extended Comfort Footwear Offers non-insulated protection to keep you dry and cool in warm and moderate conditions, during high activity levels. It ensures durable waterproofing and breathability for people who need to minimise heat retention. Benefits: - Optimum combination of breathability and waterproof protection - Dry, comfortable and cool feet, even in hot conditions and intense activity - Designed for all activities in moderate to warm conditions for intense activity and everyday use - Everyday comfort and protection for indoors and out - ACTIVimpact Technology The ACTIVimpact Technology system is a construction process that uses materials that help absorb the negative impact of the soil. This reduces stress on the lower extremities and allows you to transfer energy more easily to the activity at hand. - Interactive Kinetic System Interactive Kinetic System, an outsole design that simultaneously increases traction and allows for greater shock absorber absorption on the trail. The IKS outsole features five concave impact zones that compress and absorb energy when they hit the ground, allowing secondary lugs to contact the road, further increasing traction. - Presa Presa is the final result of internal R&D research on the sole. An environment of technological exploration and innovation, where experience and scientific research merge. This is Scarpa's approach: an R&D department to study, analyse and develop the best soles. Presa combines midsoles, composites and design to get the maximum performance from a sole, it is in fact the careful blending of these three elements that makes Presa products so innovative. - SuperGum Exclusive to Scarpa the SuperGum rubber compound was developed to provide equal or better slip resistance compared to other high friction rubbers, but with far superior abrasion resistance. It was formulated to offer high friction performance in both wet and dry conditions, but at the same time offers 3 times more abrasion resistance.
