C-Skins Legend 4mm Thermal Wetsuit Socks

C-Skins Legend 4mm Thermal Socks with Thermotech Polypro lining will help to keep your feet warmer for longer. The design of the C-Skins Legend Socks has been honed over the years to ensure optimal fit and comfort. 

These socks can be worn with snorkelling/freediving and body board fins (depending on size/fit of fin) or as possible alternatives to footwear for open water sea swimming in colder waters.

As with any neoprene accessory worn for added thermal protection, these socks would generally be worn fairly snug. This ensure the Legend Socks provide a snug fit/seal around the ankle up to the lower shin helping to reduce water ingress. The 4mm neoprene will also give more buoyancy to the feet - something you may want to be aware of if using the socks for swimming. 

Your usual shoe size is a good indicator to size required, although in most cases (no two people are the same !) if you are a little between sizes you may prefer to opt for the larger size. 

Over the years the C-Skins Legend socks have proven to be our best selling neoprene socks and are used for numerous water sports but in more recent times have become the go-to socks for open water swimming use.

C-Skins Legend 4mm Thermal Wetsuit Socks Features

  • 4mm Double lined neoprene
  • Glued and blindstitched seam contruction to reduce water ingress and encourage warmth retention and great for year round use.
  • C-Skins' Thermotech Poly Pro lining provides that cosy feeling while wicking water away to help keep feet warmer for longer.
  • C-Skins' reinforced dura flex sole helping to protect the feet by providing some abrasion resistance without loss of flexibility.
  • In most cases (no two people are the same !) if you are a little between sizes you may prefer to opt for the larger size.
