Thank you for viewing! Instant purchase without comments is welcome! For Crocs: W6 corresponds to 22cm in Japanese size. For those with an actual foot size of 23-23.5cm and narrow or regular foot width, a size smaller than their actual foot size, 22cm (M4/W6), may be recommended. I think even those with narrow feet who usually wear 23cm can wear them. *Because the size feeling of Crocs shoes varies depending on the model, it is recommended to measure your actual foot size and choose accordingly, rather than relying on the size of the shoes you usually wear.
