The boot version of Bridgedale's Storm waterproof sock

Outdoors sock specialist Bridgedale has developed its first waterproof range.

The Storm sock collection will be in shops from May and uses a HydroTech membrane to keep the user’s feet dry.

Bridgedale said the new Storm range has been designed and tested to perform to the highest standards in the wettest conditions when hiking, biking or running.

“Continuing to build on Bridgedale’s century-long sock making heritage, the 100 per cent waterproof Storm sock guarantees foot protection and comfort on the wettest trails,” it said. “Even though Bridgedale has been keeping feet warm, dry and protected for many years, providing a good level of water resistance, this is the brand’s first 100 per cent waterproof sock range.

“Using the latest production processes, the Storm sock combines advanced yarn technology with progressive design to ensure the waterproof, extremely breathable and windproof Storm sock never lets down any outdoor enthusiast.”

The construction uses an inner sock with up to 60 per cent merino wool for its anti-bacterial and anti-odour properties, combined with wicking synthetic fibres to deliver a stable temperature and move moisture from the skin’s surface. The lining has a terry loop underfoot cushion that extends around both the toes and over the heel.

Over this, the HydroTech membrane is a waterproof, breathable, high-stretch and windproof permeable membrane, which is laminated to the inner and outer layers

The nylon outer protects the waterproof sock against abrasion from footwear. Lycra provides stretch for a snug, comfortable fit and to prevent the sock falling down during activities. As well as Lycra running through the inner and outer sock, it is also added around the arch of the foot to keep the sock firmly in position, reducing any bunching or rucking inside the shoe or boot that could cause irritation.

The waterproofing rating for the membrane is better than 8,000mm hydrostatic head, and it has a moisture permeability of more than 12,000mg/sq m/24hours.

The socks will come in three lengths: ankle+, boot and knee, and three weights, from lightweight through to heavyweight.

Prices will range from £32 a pair for the lightweight ankle socks to £45 for the knee-length heavyweight version.
