The CASTELLI ESTREMO overshoes are specially designed for the coldest days, when most cyclists opt for the turbo trainer. This model represents the pinnacle of warmth and protection thanks to its Gore-Tex Infinium™ Windstopper® outer layer with fleece lining, combined with a full inner Polartec® Power Stretch® lining. This construction provides exceptional thermal insulation while allowing excellent breathability.
The CASTELLI ESTREMO is the warmest overshoe in the brand's range, ideal for extreme conditions. The Gore-Tex Infinium™ Windstopper® fabric effectively protects against wind and water, while providing optimal ventilation. The Polartec® Power Stretch® Pro™ lining keeps your feet warm, while reflective details enhance visibility. The YKK® AquaGuard® zip and the durable material under the foot ensure long-lasting protection and a long service life.

"We've had several outings in temperatures of around 0°C . This overshoe protects from the cold, but nothing more. I wear size 43 shoes, so I went up 2 sizes. It's still tricky to put on.
