The ROTOTO Coarse Ribbed Oldschool Crew Socks are inspired by authentic American tube socks from the late 1970s, reinterpreted through ROTOTO's meticulous Japanese craftsmanship. Knit on a rare vintage knitting machine that is increasingly difficult to find today, these socks use low-count, supple cotton yarn to achieve a chunky rib texture with a soft, broken-in feel from the very first wear.

What makes this model truly unique is the silk pile lining at the sole, engineered for exceptional comfort. While the outer surface is made from colored cotton, the inner lining uses undyed silk finely knit into a pile structure — fully enhancing silk's natural properties: moisture absorption, heat retention, and temperature regulation. The result is a sock with a distinctive, bouncy underfoot feel that only ROTOTO can create.

The coarse ribbed construction delivers a strong vintage aesthetic that works effortlessly across styles — from skater-inspired sporty looks to classic heritage and traditional outfits. Despite its retro roots, the balance of materials keeps the sock light, breathable, and comfortable for everyday wear.

Due to the delicate nature of the cotton outer surface, this model is more sensitive to abrasion, especially when worn with leather shoes. To preserve the fabric and extend its lifespan, ROTOTO recommends turning the socks inside out and placing them in a laundry bag before washing.
