Thank you for viewing. sidas Uchippa Product Name: UTIPPA TOWEL Color: Icy Gray Size: XS (22cm - 23cm) ★ This is likely the smallest size sold, but it runs a bit large. I recommend XS for women and those with narrow feet, up to a foot size of 23.5cm. These are used, having been worn with socks for a full day in my room on a wooden floor. During inspection for the photos, yellowing was noticed on the inside of the slippers. It's unclear whether this was due to my usage or was present from the beginning. These are offered in their current condition and price to those who understand. They will be sent in the brand's original box.
