Merino wool padded thermal knee high waterproof socks! Premium Merino wool cushioned terry loop at the soles of the socks keep your feet dry and super warm in cold weather. Like walking on a cloud! 

What is Merino wool really good at? It helps keep your body at a stable temperature. When it’s cold outside, the natural crimps and bends in its fibers trap air, insulating your feet. When it’s warm outside, it transports sweat away from the skin, helping to keep you cool and dry. These knee high waterproof socks are ideal for water crossing activities and sports.

Reusable, Removable, Adjustable Water Stop Seal Belt

As the name suggests, a water stop seal belt acts to stop water from going into your waterproof socks from the top. These light weight & easy to carry water stop seal belts are totally game changer. They provide extra water protection for sock cuffs of waterproof socks. 

Your must-have for cycling, MTB and running on heavy rainy days, or waterfall hikes and stream/river crossing! Absolutely a comfortable and flexible solution for all of your leaky waders and shoes!


  • Please don’t use these removable seal belts on other waterproof socks.
  • In order to ensure the sealing effect, we used a very strong hook and loop. Please DO NOT touch the hook side to the socks to avoid fuzzing.
  • The hook and loop part will become a little fuzzy after use, it does not affect the adhesion, these belts are reusable.
  • When you continue to use the water stop seal belt for a long time, or you feel that the water stop seal belt is too tight, please loosen the belt.

Breathable & Windproof & Waterproof Socks

Merino wool inner lining also helps keep you feet sweat-free and dry. Merino wool transports sweat and moisture away from skin as a vapor. Merino fibers are inherently porous. They’re composed of little plates that moisture vapor can get in between, meaning you're not left feeling wet, cold and clammy after a workout. Merino wool helps you stay warm and dry when you’re moving outdoors.
