Excellent condition ★ Cole Haan Ballet flats 7 1/2 B According to the size chart, this is a Japanese size 24.5cm, but the "B" indicates a narrow width. I have wide feet and am a 24cm, and these were a little tight, so I think they would be better suited for someone who is a 23.5cm or a regular 24cm. Used only once for 2 hours. Please understand that these are used and have been stored at home before purchasing.
