About RoToTo Zero Day “Hike Trek Crew” Socks

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.

Despite this development process, these are flexible enough to be worn in the city with boots or trainers, making them an ideal everyday sock. They’re made from Merino wool and feature arch support and a three-dimensional structure, which all combine to give supreme comfort and durability.

RoToTo socks are manufactured in the Nara Prefecture, Hiroyu, Japan using vintage knitting machines brought to Japan from the USA in the early 1900s. Avoiding mass production, they support skilled craftsmen and women who operate these machines manually and have developed a deep knowledge of their materials and manufacturing processes. Made with comfort and functionality in mind, the 3 Strikes socks are designed to be “lifelong consumables”, to be worn hard, and to take whatever you throw at them.


RoToTo socks come in two sizes, Medium and Large. As a guide we recommend choosing your size based on your UK shoe size.

  • UK7-9: Medium
  • UK10-12: Large
