RAFFY SWEAT SOCKS R LOGO

These soft pile-knit cotton socks were knitted with reference to the fabric of vintage sweatshirts. Inspired by the felt patches sewn onto sweatshirts, the letter "R," the initial letter of ROTOTO, is knitted using a pattern called a cut boss on a sock knitting machine. These socks are playful and have a vintage sweatshirt-like feel.

This item is made using an uneven cotton yarn called RAFFY, which is made by blending 25% long fibers with spun cotton (short fibers) and has been produced in a domestic spinning factory using the same method for over 50 years. It features a unique uneven texture and touch, and the uneven appearance that cannot be spun by modern mass-produced spinning machines creates an atmosphere similar to that of sweatshirts from that time.

These chunky slipper socks are knitted with a machine used for ski sock manufacturing between the 1980s to the early 1990s. As ski socks have become thinner because of the improvements in ski boot technology, the quantity of ski socks made with this machine has been reduced. Currently this specially-designed machine is used to knit socks for fishermen, woodsmen and other workers in the cold areas. This item is made of the same material of those worker’s socks, thick wool/acrylic blend yarn, and features a brushed sole for extra cushioning and heat-retaining properties. The rubber print on the sole helps prevent slipping.

Our double stripe slub sock's fabric is made of a mix of two different yarns to create a heather color, dirt and fuzzballs don’t stand out on the surface even after repeated use. Some people think slub socks are the best of all because of the practicality and timeless appearance. Therefore we would like to make this pair become one of ROTOTO’s signatures. Knitted with a mix of eco-friendly organic cotton slub yarn and recycled polyester yarn, the fabric provides both the comfort of cotton and the quick-drying properties and durability of polyester.

[Organic cotton slub yarn]

With help from a spinning mill in Osaka, we created this yarn after repeated trials in selecting the blend and thickness of the yarn as well as the slub width. Each yarn is carefully and slowly spun by skilled operators with an old spinning machine that has been used since the 1950s.

[Recycled polyester yarn]

This yarn is made from recycled plastic bottles once used in Japan. Because we would like these socks to be worn for a long time, we actively use highly transparent materials to ensure its eco-friendliness, quality and traceability.

The design of these jacquard socks is inspired from traditional fairisle sweaters crafted in Fair Isle, Scotland.
