Coarse Ribbed Oldschool Crew SocksDesigned 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.
