The new Scarpa Delta boots are luxury for your feet. With well known elements of Scarpa's boot making heritage, like full grain calf leather uppers and superb last (boot shape) for comfort the Delta also features the new Activ Fit. Combining four elements; last, sole, ergonomic design and footbed, ActivFit provides a new level of instant, out of the box comfort and performance. The boot uppers also feature 'mini speed' lacing, where the lacing rings have a rolling action that allows the lace tension to spread equally across the lacing area. This translates to easier more comfortable fitting across the top of the foot. Not only do they feature quality Scarpa leather uppers, the boots are lined with Gore-Tex for guaranteed waterproof and breathable qualities. A Vibram sole with PU for cushioning finishes off the boot and the midsole is reinforced with an additional moulded thermo plastic shank (TPU) and finished with the Vibram outsole.
