These room shoes are for those who wear approximately size 22.5-23.0. They are knitted with yarn made of 70% acrylic and 30% wool. Care instructions: Hand wash or use a laundry net. I knitted them carefully, but as I am an amateur, please understand that there may be some unevenness in the stitches. *Size is approximate, so please refrain from purchasing if you are looking for perfection.
