Kitz-pichiler Room Shoes - Red These are warm Austrian mountain hut slippers (shoes) from Kitz-pichiler, made of 100% wool. The soles are made of felt wool impregnated with rubber, which prevents cold air from penetrating. Also, since the ankles are wrapped in wool, these are highly recommended for those who suffer from cold feet. I received these as a souvenir from my family who traveled to Austria, and I have tried them on a few times. Outer size: Approximately 27cm x width approximately 9.5cm Suitable size: Approximately 25.5 - 26.5cm. Since they are wool, they will stretch slightly. I am also listing other smaller sizes.
