Bought these used in Japan, so they are a JAPANESE SIZE 5, (24.5cm - see chart in photos). **runs small** I am a US women’s 7.5 and the fit was tight. The top of my foot was very tight, (perhaps because of my high arches), and caused me discomfort. It’s unfortunate because everything else was perfect and they look so good… I’ve worn a few times, but, again, bought these used, so I’m not sure of the history. They look great other than some regular wear! Insoles have been replaced.
