What is Hydrostop?Updated 2 months ago

Our unique Hydrostop technology creates a barrier to water ingress around the cuff of the sock, providing a secure fit between the sock and your leg. 

Hydrostop is a soft elastic taping positioned at the inside cuff of the sock. Providing a secure comfortable fit and enables the sock to fit close to the skin and minimises movement and slipping during activities. Hydropstop also assists to reduce water ingress at the cuff of the sock from moisture running down the leg.

Sealskinz waterproof knitted socks are crafted as a three-layer product, consisting of a durable outer fabric, a soft comfortable inner layer for insulation, moisture wicking and comfort and fused between these two layers is a hydrophilic waterproof membrane. It is this hydrophilic waterproof membrane that keeps your feet dry and allows high breathability.

The hydrophilic membrane is present throughout the product up to the stitching located at the cuff of the sock (this can be seen by turning the socks inside out). Sealskinz waterproof socks are guaranteed waterproof up to the stitching at the cuff where the Hydrophilic membrane ends. Hydrostop is positioned above the stitching at the cuff of the sock and does not create a watertight seal so it is not recommended that socks are fully submerged underwater above this level.

If fully submerged in water above this level the inside of the sock is likely to become wet. If greater coverage up the leg is required Sealskinz waterproof socks are also available in knee length options.
