キッチンママ 5 These fit PERFECTLY for someone with 22.5 cm size feet. As another (Japanese) reviewer has mentioned, if you have feet larger than that, it might actually feel a bit small. I think someone with feet over size 23 would find these a bit tight. Because they fit so well, there is no slippage whatsoever, and they feel like decent quality. If you've always struggled finding socks the right size due to having small feet, I would strongly recommend these!22.5の足にピッタリです!でも23.0~の方には、小さすぎるのではないか?と感じます。いつも他の靴下?下着屋さんからの22~24とか、22~25サイズの靴下を履いていましたが、必ず!かかとからすべっていました。この靴下のサイズがピッタリしていますので、かかとから全然すべないです。22~23の方には、大進めです!
