Fourth Element Finsocks Diving Boots


Manufacturers Description


The Fourth Element Finsocks are a comfortable sock liner for either full foot fins, neoprene boots or even under a drysuit undersuit. Performance fabric and simple design minimise chafing and virtually eliminate the risk of developing sores or blisters through friction.

Fin socks aid donning a wetsuit by providing a low friction surface enabling feet to slide through the legs of a wetsuit. These socks will also help you to walk across sharp or uncomfortable terrain without the need for waterproof shoes.

Finsocks keep your feet warmer by using Fourth Elements Thermocline material which acts similarly to a 2/3mm wetsuit by trapping a layer of warm water next to the skin.

They are also ideal for children and young adults whose feet are still growing as they can help a pair of fins which are a little too large fit better and last longer.

These socks prevent against wetboots/fins rubbing when doing multiple dives per day over many weeks in warm waters. They were an absolute lifesaver for me on my recent trip and my feet were protected when in the past I've had real issues. They also are toasty warm for my normal UK diving in a drysuit.

I am now on my third pair of these socks. They completely eliminate blisters when using fins and are very comfortable. My criticism is that the stitching wears away, a hole develops and sand gets in between the layers. My guesstimate would be about 20- 30 hours of use before they start to deteriorate. At £30 they also seem rather expensive for what they are. So even though the durability is less than I would like, I keep buying them because they work so well.

These make it nice and easy to slip into my wetsuit , and also stop any rubs from boots and fins. Good quality and look robust and well made.

These socks have a great feel to them - high quality, comfortable, seamless inside - have yet to try them with fins in the water but I'm confident they will help reduce or even eradicate blisters. 4 stars rather than 5 because these are over-priced for what they are, regardless of the quality and benefits.
