With an upper created predominantly of leather, these knee-length boots have a cozy fleece lining and padded insole. Water-resistant with a thermoplastic elastomer sole known for resilience and flexibility, you will feel snug and smug zipping these up. The R6581 has two zips; the one located on the inner side of the shaft is for attachment, while the back one cleverly hides an extra panel which gives additional legroom as required. Decorated with a chunky zipper, you can choose how far up to zip them.
