The size didn't fit, so I haven't used them much. There's no noticeable damage, so please consider them for everyday use (*^^*) Japanese size: 24 cm *Fits perfectly with thin socks at 24.5 cm, would prefer a size up. Because the material is made of sheepskin, it excels at absorbing and releasing moisture. It keeps you warm on cold days and absorbs moisture like sweat on warm days, preventing stuffiness and keeping you comfortable. They can be used as room shoes (slippers), and the outsole is made of rubber for durability, allowing for outdoor use.
