RoToTo Zero Day “Hike Trek Crew” Socks – Olive

RoToTo Zero Day “Hike Trek Crew” Socks were originally created for the RoToTo head designer’s professional trail runner friend. They’ve been tested to the extreme, with prototypes for this model worn on the Continental Divide Trail. This race is known as one of the most challenging races on the trail running calendar and sees participants run 50km through the Colorado wilderness, climbing to heights of well over 3000m. Worn prototypes were investigated and used to refine the sock into the hardest-wearing sock you’ll find anywhere. They’re made from Merino wool and feature arch support and a three-dimensional structure, which all combine to give supreme comfort and durability.

  • 79% Merino wool, 13% polyester, 5% nylon, 3% polyurethane
  • Designed for comfort and durability
  • Inspired by trail running, but flexible enough to be worn casually
  • Shrink resistant
  • Moisture-wicking to keep your feet cool and dry
  • Made in Japan

RoToTo socks are manufactured in Hiroyu, Japan, with each pair designed around a “lifelong consumables” ethos. Made with the combination of old and new manufacturing processes that bring together vintage American knitting machines imported to Japan in the early 1900s and modern materials and technology, RoToTo’s socks are the finest you’ll ever slip your feet into.

The brand avoids mass production and supports skilled, local craftspeople with a deep knowledge of their craft stemming from decades of work in the garment industry.

We’ve been wearing RoToTo socks for years and their comfort and durability are second to none. We’ve tested them during long hikes in the Northumberland hills; the choice of materials and quality of construction means they are tough and comfortable enough for all-day wear.

Equally at home in the city or on the trail, RoToTo socks will keep your feet looking and feeling good and will quickly become the socks you always reach for.
