I don't know if these were designed to be used for slippers or not, but orthopedic slippers were REALLY expensive.  My husband needed something that gave better arch and heel support, and wasn't likely to wear out.  He had a cheap knock-off pair of "Croc"s that he wears outside for yard work, and liked their molded bottom.  I bought these for him, hoping they would be a good fit to help with his feet.

So far, after one week, they are terrific.  These are exceptionally well made, soft inside, molded so the softness won't "flatten out" as they do with most slippers, and they have great traction on tile floors.

Definitely worth it, and a good price for these especially.
