The Rooster Supertherm 4mm Neoprene sock - designed to keep your feet SUPER warm! The superstretch neoprene outer allows these socks to span several shoe sizes making it easier for you to find the correct size - a closer fit means warmer feet! Inside the sock there is a super soft, grey marle, quick-dry lining which not only improves the thermal qualities of the sock, it also feels very soft and comfortable next to your skin.
 
The sock is glued and blind-stitched to prevent cold water flushing, with a comfortable seam layout designed to maximise comfort when wearing.
