Cariuma Therma is water-repellent and crafted for total warmth. (So cozy, even the insoles are lined.) Therma is handcrafted using high-performance vegan suede and a cozy, ultra-plush vegan shearling lining, made from GRS-certified recycled materials. These high tops feature a natural rubber sole, stitched to the upper for extra durability. Never worn.
