Kamik is a true professional when it comes to winter footwear. Known especially for its super warm Canada Boots, they also manufacture models like this, aiming at more urban use. The manufacturer reports a lowest recommended using temperature for their shoes, and for this model that sits at -20ºC - keep in mind situations and people differ a lot, so we can't guarantee you'll be ok in that weather. The surface leather used in these shoes looks lively even when new - the impression is that of a rough and ready to go boot, instead of a polished one. - Surface material: high quality leather - Waterproof DriDefense membarne - Shaft height 16.5 cm - Ortholite Hybrid ECO insoles - Felt cuff - Heat-MX insulation - Warm and moisture transfering fleece liner - Shock absorbing EVA midsole - The outer sole is made of genuine natural rubber - this won't harden in frost like many other materials.
