Vick is a practical and stylish winter boot. The uppers are made of waterproof nubuck, and the inside is lined with vegan wool to keep warm. The simple silhouette means they can even be a bit dressy if need be. Olang claims a temperature rating of -30°C (take that with a grain of salt, as that will be different for everybody; it will depend on several factors, including your circulation and socks). The best part of these boots may be the outsole: it features Olang's HOOK outsole, with 16 stainless steel pivoting and folding cleats (see the first and fourth picture). Olang does provide a special pry tool so you do not have to use your hands to operate the cleats.
