I've been wearing these Klagn wool felt clogs for nearly three weeks now. They are excellent clogs. They're light and very comfortable. They take just a second to put on or off. They easily stay on my feet. I'm usually a size 12 to 12.5 in US shoes, and the size 46 European fits perfectly. I wear them in and around the house all day, but I think you could easily wear these in a work or hospital type of environment. The sole is thick, so I think they'd be fine for outside wear. They also have some toe protection. My experience with wool clogs is that they're great year-round, the wool breathes and is comfortable in hot weather. I'm happy with these clogs.
