Conrad Natural Tundra The Conrad Natural Tundra is constructed with organic cotton and ethically sourced raw materials as well as rough-cut overstitched seaming for a relaxed , natural look. The Ridgelight sole gives the impression of a narrower shoe but maintains a relaxed wide fit which guarantees that it will be one of the most comfortable boots you will ever wear. The Natural collection uses the vegan-friendly, cork-lined Coco Soul anatomical insole, instead of HEYDUDE\'s usual leather-lined insoles. This insole can be removed and wiped clean whilst the shoe can be put into a cold machine wash when needed. Material: Textile Sole Unit: RidgeLight Weight: 190grms Features: Relaxed wide fit Machine washable cold Removable anatomical cork lined \'Coco Soul\' insole Rough cut oversized finish Dual lace option
