The Arriba 2 GTX is a new model greatly enhanced to offer a much more comfortable fit and enhanced cushioning & support. Using a new AKU last for a wider forefoot & narrower heel the Arriba 2 feels instantly comfortable straight out the box. Comfort is further enhanced by the IMS 2 system, a 3D midsole cradles the foot providing stability & a layer of EVA foam on top of the midsole provides instant comfort. A further layer of moulded PU beneath the midsole takes care of impact forces enhancing wearer comfort. IMS really does make a massive difference to your comfort & support, your foot is held securely even under testing conditions reducing fatigue & stress. The uppers are made from a Suede & nylon 3D Airmesh fabric to provide durability & breathability & are backed with a Gore-Tex lining for complete waterproofing. Traction & security is provided by a unique Vibram sole unit which is both hard wearing & grippy in all conditions. A superb lightweight shoe with unique technologies & components providing superb comfort, stability & support.
