T3 Thermal Bootie

Works decently, but tight around the calf, making it a little tough to zip up unless you have skinny legs. For reference I got a size large, and I’d say my calf circumference is fairly average. The material will stretch with a little work. I appreciate how the membrane covers the vents on the bottom of my shoes, but I will say the material under the sole is very delicate. I anticipate having to repair them at some point from damage while clipping in/walking around.
