Why? Our warehouse is chaos-organized. The same sizes/colors are not placed in the same location. We save money in our handling when we only have to pick from one location - that's why the quantity discount only applies to the same size and color. Consider it a bonus that we share the savings with you.

If you've tried it, you already know how annoying it is. In other words, having heavy and wet swimming socks that nearly falls off almost as soon as you get out to swim open water swimming. We have. And we have solved that with these Calder Pro Neoprene socks, which are part of our top-range. Extra long up the leg, velcro strap, very elastic 2mm neoprene that sits snugly on the feet and non-slip bottom, all this you get from our most popular neoprene socks ever, Calder Pro.

If you've tried it before, you know precisely how annoying it is - i.e. when water gets into the swimming socks, so they almost feel like two bags of water on the feet, and in addition do not provide the warmth that is otherwise intended.

You will without a doubt avoid that with these Calder Pro Neoprene socks, which are made specifically for use during open water swimming.

What makes these socks so good is

  • That the socks are made with extra length up the leg, so that they can be tucked under the wetsuit, so that there is no skin on the feet that comes into direct contact with the cold water.
  • That a unique velcro strap has been added at the top, ensuring that you can tighten the socks in and you will thus avoid them falling off or feeling like they're about to. In addition, it closes off so that the cold water can get into the sock itself.

In addition, the following key features can be mentioned

  • The socks themselves are made from 2mm high-elastic neoprene, which makes it almost feel as if you are not even wearing them while swimming.
  • The neoprene is made from the best Yamamoto neoprene, which comes from Japan and is the kind that the specialist wetsuit manufacturers use, as it is known for its flexibility and heat-building function.
  • The sole is made of a durable material, so you can walk on concrete, sand, stone and the like. on the way down to your swim without them breaking or making holes in the bottom.
  • The inside of the feet is made of comfortable nylon, which makes them warm and comfortable to wear.
  • They are made to fit snugly on the feet, so that you can maintain your normal strong leg kicks.
  • Made to be used all year round.

    They fit well and are nice warm

    Jannie Lærkesøe

    I am impressed by how warm my feet are in the sea with these "socks" on. I just started my winter swimming adventure... the water was 10.6 degrees and I could stay in the sea for a long time because of warm feet🥰 Thank you for your product.

    Didn't keep the cold well. But the seam burst on the foot after just a few times. But with a smooth complaint, a new passport will soon be that I hope has better quality
