Ugg is an American footwear company, specializing in the production of boots, which have become famous all over the world and are very trendy. The original idea of the product arises from the need to warm the feet of surfers once out of the water; so the founder of the brand, Brian Smith, created a shoe made of hand-stitched sheepskin and a sole. The shoe is also suede on the outside and wool on the inside. Ugg boots, very popular even between takes in the Hollywood backstage, are able to offer a mix of relief and comfort that defies any definition.
