Olang Ziller Tex OC is a classic and timeless two perfect words to describe this style of winter boot. The Ziller will see you through the winter months, helping you fulfil all outdoor activities. An Olantex water resistant membrane is used to keep you dry, whilst the wool lining will keep you warm, a perfect combination! Even fitted with the OC anti-slip system, this sole with its built in on/off ice grip will help you when walking on icy or snowy conditions.* Please note: The sole of this boot is all black.
