Three-layer fully waterproof socks with a mid-calf length. The Hytherm Pro socks are designed for outdoor activities in freezing winter conditions. Their waterproof protection is achieved with a Porelle membrane, while the thick inner layer of warm merino wool provides superior comfort and insulation.
Socks are suitable for winter hikes or biking, for work around the house, skiing, cross-country skiing, etc. Thanks to their water resistance and windproof properties, they are much warmer than regular socks. Everything is further enhanced by the inner merino layer, which additionally has a natural antibacterial function.
We personally use these socks with trail running shoes during mountain crossings in cold weather and winter, something we wouldn’t attempt with regular socks. They also work perfectly in wet terrain and rain, keeping our feet dry. During long hikes, they help prevent blisters caused by walking with wet feet. Despite being fully waterproof, the socks still maintain good breathability.
We recommend reading our blog article about the use and selection of waterproof socks.

The socks can be machine washed on a gentle cycle with regular detergents at a maximum temperature of 40°C or hand washed.
Do not dry the socks directly on a heat source like a stove, fireplace, or radiator. Instead, dry them near a heat source. Hang the socks to drip dry. First, let them dry from the inside, then turn them inside out and dry the outside. Do not wring or twist the socks to remove water.
