These appear to be great at first, but after several weeks of wear, I'd have to agree with two comments:  they feel as though the foam is slipping around under my foot, kind of a disconcerting feeling, and YES...why do manufacturers INSIST on stitching tags right under your heel?  I thought it wouldnt be too bad at first, but its starting to be more noticeable.  So hard to find a decent slipper nowadays.

Update 12/2013 - yes, these flat out suck, pad inside is separating, holds foot smell, no way or washing.  See picture to see what is happening.
