While some retreat to indoor trainers or skinny skis during the off season, there's a select bunch of die hard riders that won't give up two wheels and fresh air. For that frosty contingent, Gore Bike Wear offers the Road SO Thermo OverShoes. Not only do these shoe covers offer wind protection, they have thermal properties to keep you comfortably spinning pedals in sub-freezing temps.A thermal lining retains heat for comfort, and it also pulls perspiration from your socks to help prevent clamminess against the skin. From there, moisture is pushed to through the WindStopper membrane where it's quickly evaporated. The beauty of WindStopper is its unique ability to allow perspiration to escape while stopping cold wind in its tracks. This combination of warmth and wind resistance gives you the ability to use highly breathable, summer-optimized shoes in the dead of winter.For durability, Gore equips the Road SO Thermo Overshoe with abrasion resistant materials in key areas such as the pedal/sole interface and along the toebox. A rear entry zip make pulling these Overshoes on struggle free, and a hook-and-loop ankle strap ensures you can lock the weather out. As a winter layer, Gore hits the Road SO Thermo Overshoe with plenty of reflective elements for low light safety.The Gore Bike Wear Road SO Thermo OverShoe comes in five sizes; Small through X-Large and two colors; either Neon Yellow or Black.
