While we're always a little hesitant to describe any product as extreme, Garneau's new Thermal Extreme Shoe Covers certainly live up to their name. The covers were made with a blend of durable and insulating fabric panels that work as a barrier system to keep the coldest, wettest, and nastiest weather conditions from reaching your feet. The Thermal Extremes were constructed using 3mm SBR neoprene. Compared to standard neoprene, SBR features a water resistant polyurethane laminated with fleece, with each panel joined using sealed seams. However, similar to standard neoprene, it still has a dense, rubber like structure that provides both strength and insulation. The extended cuff design provides more coverage than standard shoe covers, as well as a fit that prevents water infiltration. Garneau added its soft Flex Zone paneling below the front of the cuff, making a smooth, pressure free transition between the stiff neoprene material across the top of the foot. The covers extend above the ankles and were sealed off in the back with hook and loop closures, further protecting your feet and lower legs from the elements. Additional hook and loop fasteners were added under the soles, which makes the covers easy to pull over your shoes. To increase the covers' durability and abrasion resistance, Garneau strategically placed panels of Kevlar reinforced material under the toes. The covers were finished off with reflective elements in order to increase your visibility to motorists in low light conditions. The Louis Garneau Thermal Extreme Shoe Covers are available in the color Black and in five sizes from X Small to X Large.
