My wife bought these slippers as an alternative to my normal brand.  I hate them.  They are actually too large, probably because of the 11-12 range instead of a single size.  When I wear these slippers, I feel the cold from the marble floors coming right through the bottom, they provide no insulation and no padding.  I will never buy another pair of this brand, at least not for men.  My wife owns a different pair of the same company and her slippers are good but they same insulation and padding issues.
