I have wanted to try out Haflinger slippers for the longest time but they are pricey and if they didn't work for me I hate the hassle of making a return. Anyway, I finally succumbed to this pair bought from Amazon in size 41/10 which is my regular size. The size was correct by the way but I have narrowish feet and that was my big concern because I have gotten the impression from reading many reviews that this brand of slipper runs wide. I chose this one because at least one reviewer stated that it was too narrow so I jumped on it. Since they are backless (a style I do prefer) if they are too wide they are not secure on your foot. Another problem I found with this style was a seam running down the center of the top of the slipper. When I had them on, I wanted to have this seam between my toes somehow but because it ran right down the center it didn't really fall in a comfortable place so my foot was either too much on the right or the left of the slipper. I love boiled wool but these slippers were not a good choice for me. I wound up getting Tamarac red shearling-lined booties that I really love.
