The perfect swim socks to help you keep warm in the cold water

This absolutely perfect neoprene sock is one of the warmest you can find on the market. It has everything it needs to be the best. It is perfect for men and women who freeze their feet when swimming in open water. Not only that, but it is made with a full 3.5 mm neoprene, which really ensures that you can keep the heat. The sock is a bit thicker than the previous model from zone 3, from 2 mm to 3.5 mm.

The sock is very tight-fitting, and it will not be possible for water to get into the sock in any way. A thermal lining ensures this. It completely shuts off the water, but is still very comfortable to wear. In addition to this, there is a Velcro strap that ensures you can find the right fit for you.

The sock is made with a titanium lining that reflects body heat and ensures that your body heat will not be wasted when you swim.

The seams, which are the ones on the side of the sock all the way down, are glued and double-blind stitched and the outside is secured. All this ensures that the water stays out of your sock.

Overall, a good design that does not compromise on warmth. The liquid sealed seams and the circular seal are excellent features that help prevent water from getting through.


  • Thicker than the previous model, from 2 mm neoprene to 3.5 mm.
    Impossible for water to enter the sock
  • Reflects body heat and ensures that your body heat will not be wasted
  • Velcro strap that ensures no water gets into the sock
  • Sealed seams and the circular seal
  • All in all, the ultimate neoprene sock that retains warmth
  • Good all year round

So if you freeze your feet when swimming in open water, this is definitely a necessity.
