I purchased these slippers for my father-in-law who has peripheral neuropathy in his feet and legs. He absolutely loves them and wears them all of the time inside the house! They stay on his feet well and with the Velcro he can adjust them, as needed end for swelling. The sole is flexible and not slippery. He especially likes that they don't look like something orthopedic or just for someone who is elderly. They look like cozy, comfortable slippers.
