Didn't plan to buy shoes in Japan as imports are so expensive. Nonetheless I went to Isetan for a stroll while husband was out shopping for fishing gear and came across these. Number Twenty-One seems to be an in-house brand for Isetan. They are manufactured in Vietnam to keep the costs down I suspect, and some of the designs are "inspired" by other designer labels. These for instance are a dead ringer of the Aquazzura shoes I was thinking of buying (I did;t because the fit wasn't particularly comfortable). At 1/4 of the price of Aquazzura I did not hesitate. They turn out to be reasonably comfortable, would be good if there's a bit more padding on the soles. Love the straps and the color contrasts. True to size.
