This is an all-leather setta (Japanese sandal) that was sold through crowdfunding or something similar. It's made very sturdily and can be worn for a long time with repairs. The heels are worn down, so I recommend getting them repaired at a shoe repair shop (should cost a few thousand yen). I recommend it to those who are tired of ordinary sandals or zori (Japanese sandals). I think it would look cool with some casual denim and a t-shirt.
