Three-Layer Aquasealz™ Composition

Outer – Extra-durable nylon exterior, with 4-way stretch for an optimal fit.


Mid-Section – Aquasealz™ waterproof membrane releases moisture vapour from inside the sock.


Interior – Premium merino wool and acrylic blend, with terry-loop knitting for extra comfort and sweat-wicking. Natural antimicrobial properties, stopping growth of odour-causing bacteria.


A seamless construction, with elastic support on the ankle, providing a close fit.


Hydrostop™ is an elastic taping around the inside cuff of the sock. This extra barrier reduces the risk of water dripping down the leg into the sock.

Wide Range of Activities

Designed for cold temperatures, the Runton is insulative, waterproof and moisture-wicking. Hydrostop™ reinforces waterproofness, ensuring water does not trickle down the leg into the sock. A premium merino wool interior, with terry-loop knitting, has excellent thermal properties. Merino wool absorbs moisture away from the body, ensuring breathability. An engineered nylon blend exterior has similar moisture-wicking properties, highlighting the cohesiveness of fabrics within the garment. The Runton’s Aquaselaz™ membrane is 100% waterproof, sitting in the mid-section of the sock. Essential for cold, wet weather pursuits: hiking, trekking, mountain biking. The Runton is a relative of the Starston.


Accessories undergo an intensive testing process before coming to market. The combination of synthetic fibres with merino wool ensures high levels of performance with a natural feel. Hydrostop™ prevents water entering the top of the sock, affirming waterproofness.
