I want to know how to make these. Zori is the generic term for sandals, while waraji is very specific (the ones with extra go-faster straps for samurai speed). There are workshops in Japan on how to make them from old cloth, eco-zori— cool! But zori were always a re-use of industrial byproducts. Even some schoolkids make their own.
Good zori pix, and check out those boots!
