CASTELLI ESTREMO THERMAL WINTER SHOE COVERS

Designed from the ground up, the Castelli Estremo Shoecovers are the warmest booties they've ever made. Constructed from GORE-TEX INFINIUM™ WINDSTOPPER® fleece-backed fabric, which keeps the wind out while also letting more moisture escape than any other windproof fabric. A second fleece layer made from Polartec® Power Stretch® Pro™ traps heat and further bolsters the warmth. Built with an extra tall cuff to keep water and cold out, with a YKK® AquaGuard® zipper at the back for easy on/off.   Made for the absolute coldest days, the Estremo Shoecovers will keep your feet toasty from the low 40's, down into the single-digits Fahrenheit. Comboing these with a thick wool winter sock ensure your feet say nice and warm no matter how frigid the conditions.
