NEXGRIP has quickly become one of our customers' favourite winter boot brands. Ice Nat is one of their dressier options. This riding boot style features functional laces to get a proper fit around your leg, and an inside zipper helps get them on and off. They are warmth rated to -15°C (take that with a grain of salt, as it will depend on several factors including your socks, your circulation, and your activity level to name a few). The uppers are made of waterproof leather, and the outsole features NEXGRIP's exclusive metal cleat under the heel and anti-slip rubber under the toes combination. Both of those help provide excellent traction in icy winter conditions.
