Tabi are traditional Japanese footwear.
足袋 literally means “foot sack”… and tabi are considered to be between socks and shoes.
They have rubber soles and a cloth exterior and they’re buttoned up at the side. They separate the big toe from the other toes.
Often they’re allowed to be worn inside; which is a shoe no-no.
They’re still worn today, especially by taiko performers.
Sometimes you’ll see builders and other manual laborers wearing them too. These ones are more hard wearing and offer more protection. They’re called jika-tabi, 地下足袋, which means “ground tabi”.
Worn by women and men… they still can look pretty bad-ass if worn by cosplayers around Harajuku.
