Ugly yes, but Glerups are the best slippers you will ever buy: they make your feet as comfortable as possible, they are warm, but don't sweat, but don't knead indoors like flip-flops (I'm looking at you, UGG). We've had several pairs over the years, leather soles (which are fine too), boot style etc, but this style with that *specific* rubber sole was the top choice here at PNW. (Other rubber soles used to be made, but in my experience this sole has better grip, is softer and looks better.)β¦
