Unique & different, I liked them - but needed to return.  I typically wear 6.5W-7M.  That's what I ordered, but after (3) hours of office wear, I removed them to see if I had any redness anywhere. My feet swell during hot days.  Top edging of shoe cut into the top of my foot, my right heel was also red (this never happens).  These are advertised as Medium width, but should only be sold as &#34;NARROW&#34; width.  Too bad, I really liked them.
