These slippers were purchased from B-Company. They are breathable, have good cushioning, and the soles are non-slip. I bought them at the store, where they were labeled as size M (23-24.5cm), but they fit perfectly at 23-23.5cm, so I think they run small. Retail price: 2310 yen They will be shipped via Takkyubin Compact (shipping cost 520 yen).
