Product Description We’ve tested these Zone3 Heat-Tech Warm Swim socks and at 3.5mm of neoprene, they are one of the warmest available. These socks are slim fitting, have a fabric lining, and will be perfect for swimmers who wish to swim in the early spring or through the autumn/winter and those who suffer from cold feet. They are made from high-stretch neoprene to ensure a great fit and flexibility during the swim. The seams are glued, double-blind stitched, and then liquid-sealed on the external side to help ensure they are watertight and durable. Liquid seam-sealing is what sets quality swim socks and gloves apart from the rest. We also really like the ‘Waterblock system’, a circular seal at the top to help keep water ingress to a minimum. There’s also a Velcro strap to help minimise any water entry. The neoprene Heat-Tech swim socks also feature a durable gripped sole for walking to and from the water. Zone3 Neoprene Heat-Tech Warm Swim Socks Features: 3.5mm high-stretch neoprene Fabric-lined for comfort Slim fitting Liquid-sealed seams, are very important for reducing ‘flush-through’. ‘Waterblock system’ seal and Velcro strap to help reduce water intake Durable gripped sole that’s not too buoyant. Overall a great design that does not compromise warmth and doesn’t have too much buoyancy. The liquid-sealed seams and circular seals are excellent features to help stop the water from flushing through. A great pair of socks to keep you warm and in the water for as long as you can manage. NB: current available sizes are BLACK/RED Zone3 Socks Size Guide For UK Sizes. There is an official Z3 size chart in the product images, however, we tend to find the socks are roomier than this suggests. We often find the Z3 socks are more like: XS = 4-5, Small = 6 -7, Med = 8-9, Large = 10 – 11 For more advice on fit and which sock to buy, read this article: Swim Socks Size for Swimmers
