Thank you for viewing. MITSUUMA Model Number: SB831 Size: SS (22.5-23 cm) Color: Black 2-way type The opening can be folded over to create a short type (Photos 3, 4). Please search for/check SB831 for details. Purchased from Mitsuma in December of last year for ¥7,150. I wore them about 5 times, but the size didn't fit, so I'm selling them. There is slight soiling on the insole. Regarding the black bumps on the soles in the photos, these are ceramic particles (photo). Also, the ceramic particles on new shoes are bumpier, so I think they have worn down from wear. I think the probability of slipping on snowy roads is higher than with new shoes, so please be aware of this. Regarding shipping: They will be shipped in a simple package in the short length state (Photos 3, 4) in a paper bag. There may be a change from Yu-Yu Mercari to Raku-Raku Mercari.
