I got these slippers for my husband last Christmas and waited a year to write this review to see how the slippers held up over time. He loves them and wears them daily, all seasons. They have conformed well to his feet and have not lost their shape. The soles have held up well on our mostly hardwood floors and don’t tend to collect dust. He says the slippers handles sweat well and are breathable. He typically wears a size 10.5 US men’s shoe and he’s happy with the size 43.
