I have to say, I'm pretty impressed with these slippers.
I have quite a few pairs of basic suede mules, purchased previously from a local chain.  Since developing well defined heel spurs, my pod had ordered me custom orthodics, which I was wearing for over a year, in my sneakers.  I could not walk around the house barefoot or in socks without pain.  The slippers were just as painful as bare feet so I ended up wearing my sneakers around the house, right up until bed time.  I was desperate to find a pair of slippers with support.  Fast forward, I was supposed to go to physical therapy for plantar fasciitis, but as I normally do, I put it off and never went.  Still major discomfort walking, actually getting worse.  I stumbled upon these slippers and figured I'd give them a shot.  Now, I'm a womans 9.5, and would normally have gotten a mens 7.5, but these are full size only, and the 7's were $10 cheaper than the 8's, so I figured I'd test the waters and try the 7.  Surprisingly, they fit perfect, probably a bit snug, but not uncomfortable.  I've been wearing them for 2 days now, and I can actually walk around the house in slippers again!  As they're getting broken in, I can feel the arch support a lot, which is well, just amazing.
I can sit down on the couch and get up, while wearing these slippers, and not hobble like I'm old and gimpy (I'm 53 btw).
After 2 days, I am in love with these slippers.  I hope they last.  I should probably order another pair right away, but I'll wait a few weeks ;)
