“These slippers run big. I ordered a 10, my normal size in shoes and slippers. I've worn Haflinger slippers for yrs in that size, so these run bigger. Haflinger has become very flimsy with thinner wool, so tried these. I like them as they have great arch support, but wish I had ordered a 9 1/2. Highly recommend but keep in mind they run a bit big. Probably should have returned them but will wear them this winter with thicker socks.”
