These slippers have a comfortable feel with a soft 3cm thick sole. They are very light and the boa lining inside is surprisingly warm!! They can be worn as shoes, and can also be slipped on by stepping on the heel. You can wear them outside, or as room shoes/slippers indoors. *I tried them on. *Purchased for 3860 yen - Brand: CHAO - Model Name: ECAC - Size: 25-25.5cm - Sole Thickness: 3.0cm - Material: Soft material Thank you for viewing.
