Comfortable lining socks for full foot fins and neoprene boots. Constructed using flat lock stitching and fleece lined fabric, Finsocks minimize abrasion from full foot fins and allergy reaction to neoprene boots whilst eliminating the risk of sores or blisters from rubbing. Worn underneath neoprene boots, Finsocks help to keep the feet a little warmer and assist with the donning of a wetsuit by providing a low friction contact between the feet and the inside of the wetsuit. 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.
