The slippers are comfortable and warm which were two key reasons for my purchase. Information included with the slippers indicated they would initially have an odor. So, it suggested airing them out for two days. They smelled like fish. I aired them out for four days. It is now four months later and they still smell like fish but the odor has faded significantly. I kept the slippers because they met my needs and no one was around when I wore them...I was the only one who had to deal with the odor. I've only worn the slippers indoors. Yet two weeks ago, the sole on the left slipper began pulling away from the slipper and the part of the sole that pulled away is beginning to disintegrate. In two weeks time the opening went from minute to about an inch and half. At this rate, I'm not sure the slippers will last through the winter. Very disappointing.These slippers are adjustable enough for any edema issue I've ever seen.The soles are sufficient for dry outdoor useThe velcro system is brutally strong. One must have some hand strength to use it.Purchased these as temporary shoes for a slow moving individual and they work perfectly.Based upon reviews, I bought one size up, but I didn't need to. Maybe a half size if you're concerned.My diabetic grandfather was very happy with themMi mamá tiene una placa en un tobillo y no podía encontrar zapatos que se ajustaran hasta que encontramos estos, son una maravilla! Se ensucian bastante porque se les pega pelusa por el material pero fuera de ello le son muy cómodos y lo mejor se ajustan al tamaño de cada uno de sus pies.
