*UPDATE  2015: Since having gotten my first ( & second) pairs of these, I received some Vionic Bliss slippers and I find that I prefer them for arch support but the Acorns are perfectly fine as long as you don't have any REALLY MAJOR foot/balance issues. These are much  fluffier & the footbeds don't stain the strange way the Vionics tend to. Plus, It's nigh on impossible to FIND a pair of Vionic Bliss slippers anywhere anymore so I'm back to Acorn for right now at least. As for my sizing review, you may wonder, "If they were too wide & too long, why not order the next size down?", and my only answers are 1. I feel sure this is the same size I ordered before,  2. My mom.wears the next size down and when I tried hers on, they were too small  3 . I can walk in them and 4. Returning/exchanging is too much of a hassle! *

My mom got me a pair of these a few years  a year ago & I liked them so  much, I decided to get another pair, and then a third. (Hooray for Amazon sale pricing!) Each pair is just as lovely as the last & they wash well (though admittedly, with no small amount of noise) Needless to say, I enjoy all my Acorns tremendously!  They really are perfect "spa" slippers - they're so luxurious!
