About

Overview

Built for life on the road and at the beach, the FCS Travel & Surf Sock is a high-performance, purpose-built sock designed specifically for surfers and travellers. Made from premium Merino wool, it combines Nuyarn® for breathability, thermoregulation, and comfort on top, and Herculan® underfoot for unmatched durability and abrasion resistance.
Seamless 3D knitting, a split-toe design, elastic arch support, and mesh ventilation panels ensure ergonomic comfort whether you're in boots, sandals, or barefoot. Naturally antimicrobial, moisture-wicking, and fast-drying, these socks stay warm when wet and cool in the heat—ideal for post-surf recovery, travel days, or everyday wear. Sustainably made from responsibly sourced wool, they’re built to last up to 8.8x longer than standard wool socks.

About Herculan®

Herculan® is a durable, high-performance wool material designed to last up to 20 years. It manages moisture effectively to keep the body dry and reduce slip, helping prevent heat blisters. Unlike synthetics, it conceals odour, noise, and reflectivity, making it ideal for high-impact use. Made from strong wool, a by-product of the sheep industry, Herculan® offers a sustainable solution while enabling brands to develop innovative new products.

About Nuyarn®

Nuyarn® overcomes the common drawbacks of traditional Merino wool by eliminating the need for tightly twisted spinning methods that compress fibres and reduce performance. Instead, Nuyarn® preserves the wool’s natural structure, maintaining its volume, aeration, and movement. This results in greater durability, better insulation, improved moisture management, and enhanced comfort—without the issues of pilling, holes, or itchiness. Nuyarn® delivers the true performance potential of wool, even in extreme conditions.

Key Features:
- Elastic Support System™: Locks the sock to the foot and lower leg with minimal compression while providing support.
- Double Cuff: High stretch, ensures minimal compression during wear.
- Mesh & Ribs: Knitted into the sole of the sock for moisture management and temperature control.
- Alignment Points: Allowing for the correct location of the dorsal protection pad, giving protection from shoes & lace pressure
- Seamless Toe: Ridge & abrasion-free comfort, reducing blister risk during wear.
