Thermal, wind and waterproof shoecover. Zip on the back side and strap to adjust the ankle closure.Two high visibility reflective bands near the zip. Made with two layers of fabric: the outer material is waterproof and windproof, while the interior is very thermal to face the lower temperatures. The air gap between the two layers of fabric enhances the thermal insulation, keeping the foot temperature-controlled. The reinforced toe makes it suitable for both road bike and MTB.
