This is the second example that I have seen, they look like tabi but there is no bottom, they only cover the top of the foot, any ideas or guesses about what they are? A lot of work went into them, thick and quilted out of what looks like cotton. Many year ago I bought a similar pair but they were actually full tabi.
could the ones without soles be for geta on muddy days, geisha boots?
saying it that the toes are equal? Could these be for a posh horse?
Anthony and Malcolm also mentioned covers of some sort. I thought the same thing but there must have been a specific reason for bottomless ones over wearing full tabi, water may be an answer as samuai did wear geta.
