These cartoon house slippers show paired shoe-size labels, but the product text also provides foot-length bands. Use the measured foot length and the selected colour together: the text lists different ranges under women’s and men’s colour headings, while the available colour names do not match those headings exactly.

Find the stated band, then confirm the colour

Measure both feet while standing and use the longer one. For the text’s women’s group, size 6/6.5 (36/37) corresponds to 22.5–23 cm, 7.5/8.5 (38/39) to 23.5–24 cm and 9/9.5 (40/41) to 24.5–25 cm. The men’s group continues at 10/10.5 (42/43) for 25.5–26 cm and 11/11.5 (44/45) for 26.5–27 cm. A foot in a gap or near a boundary needs an actual inside-length measurement; the source does not explain the gaps or width allowance.

The selector includes Pink woman, Blue, Black, Gray woman and Brown man. These are option labels, not a rule about who may wear a colour. Ask the seller to confirm which foot-length chart applies to the exact colour/size combination, particularly at 40/41 where the groups meet. The listed flock upper, short-plush lining/insole and TPR outsole describe components, not a slip-resistance test or year-round comfort rating.
