Socka Socka is a pretty straightforward name for a sock brand from Japan. All of their socks are made in a place called Nara on special loopwheel machines. Craftsmen from Nara have been perfecting the art of making socks for over a 100 years and with these socks it seems like they've nailed it to us. These 3 layer socks with 5mm loop piles made of hyper soft cotton are ridiculously comfy and will have you feeling like you're walking on fluffy little clouds.
