Our 13" RANCHER in the traditonal style upland boot is preferred by bowhunters for its ground sensing abilities, while farmers and ranchers prize the self-cleaning nature of the Tractor Tread outsole. Comfort rated to zero degrees due to the quilted three layer removable liners made with a tough wicking synthetic layer, and 400 grams of Thinsulate Ultra Insulation, as well as 3mm wool felt. These boots are built tough, so if you eventually wear the bottoms out, they can be rebuilt at a fraction of the cost of a new pair. Another benefit of all of the Kenetrek Boots. Men's whole sizes (5-15) medium width. Half sizes round up to the next whole size, women order 1-1 1/2 sizes smaller. 5.1lbs. Made in Thailand.
