Fully insulated, waterproof, yet breathable. These are the new Fizik all-terrain winter boots that are prepared for extreme weather conditions and will protect you in the worst weather, whether you're riding on a snowy trail, through a soggy forest or on gravel on wet gravel!
the Artica GTX is waterproof thanks to the GORE-TEX Koala membrane. This membrane does not let any water in, but at the same time ventilates the moisture out of the shoe. The boots can be quickly fastened even in warm winter gloves with the easy-to-use BOA wheel and Velcro strap. The sole with a stiffness index of 5 is widened and rubberised for greater stability even on icy surfaces. The inside of the shoe, including the insole, is padded with fleece material, which ensures thermal comfort even on the coldest days and is also very comfortable.
the Artica GTX is a winter MTB boot that won't get your feet sweaty or wet when you're running through a stream.
