The Scarpa Cyclone GTX hiking boot uses a new dual injection technology that develops an exo-skeleton, elevating the upper support and protection to new levels for a direct injection boot. The graded thickness of the injection allows a progressive flex to be developed, facilitating a perfect balance between torsional support and instant forefoot comfort. The inner/ softer PU affords outstanding shock absorption and is strongly housed inside the outer layer. The new last is centred on delivering that all important instant comfort. The uppers are waterproof and luxurious Nubuck leather.
