OTK Whet Walk Boots are handmade shoes featuring synthetic upper, lining, and shaft material to keep your feet comfortable all day. The outsole is made of rubber for added durability and slip-resistance. Built with a 4.5CM-5CM square heel, and an Eva insole, they provide optimal cushioning for hours of wear. The boots are fastened using an easy-to-use zipper closure, and take 15-20 days to be delivered.
