Castelli Estremo Shoecover

Elementary criterion: warm feet

For our warmest overshoe ever developed, we had to fundamentally rethink some key points. For comprehensive wind protection, we rely on GORE-TEX INFINIUM™, a fleece-lined material that is also more breathable than any other windproof fabric. Additionally, a layer of Polartec® Power Stretch® Pro™ is used. Due to the generally thick construction, a thinner layer is applied in the toe area to avoid interference with the crank arm. For maximum warmth, this model is designed to be very high and also features solid splash protection. For the utmost comfort, we recommend our Venti Soft Sock.
