I bought these prior to knee surgery because I wanted a slipper for the hospital that fitted snugly and had good traction. These suited the purpose perfectly: easy to get on and off; the upper fitted around the foot snugly; the Velcro strap allowed for adjusting snugness; and the sole provided good traction on the hospital floors. The negatives are: the footbed was a little too thin to be comfortable so I had to add an insole; and the sole provided good traction as long as it was never worn outside. Once I wore them outside on the sidewalk a couple of times for walking therapy, the sole pretty much wore away and became too slippery to be safe. (there are slippers available that can be worn outside.) I would recommend these slippers, keeping these caveats in mind.
