New The North Face Nuptse Chukka Camo Boots, 27 cm NF02273 No box. These functional, cold-weather chukka boots support comfort during the winter season with their excellent heat retention. The upper uses a water-repellent, recycled PET ripstop material, and the insulation is 100% recycled polyester wadding, which is less likely to lose its function when wet. This construction is environmentally friendly while enhancing functionality. The heel area incorporates a cushion pad to improve cushioning and hold. The midsole uses lightweight, high-rebound compression-molded EVA, and the outsole employs Surface Control, a 10% natural rubber sole that balances durability and grip.
