Tried many slippers .... but these are really worth their money, if you are looking for something quality and "fixed" in the area. The sole is non-slip and abrasion-resistant and does not leave streaks on hard floors. The felt is really thick and solid. Not a Wabbelzeug as from the discounter. For some people with strong right "feet" and not Heidi Klum-feet :-) just buy it in higher-quality area !!! The brand name "Haflinger" is really program .....
