the rototo three stripe coarse ribbed oldschool crew socks are based on tube socks made in the u.s. in the late 1970s. these ribbed socks are knitted with a special knitting machine that is hard to find today, using low-count supple cotton yarn. the liner of the sole is brushed for a unique bouncy feel that only rototo can create. the simple design fits any types of outfits from skater-like sporty styles to traditional ones.
