This color fit as expected.  Others don't necessarily.  The dark brown was one whole size too small.  Not especially comfortable on your soles, as bumpy insole and the plastic is very hard, but the fit is comfortable (if that makes sense!!) and I have a high arch.  I do wear them all the time.  No support at all, though.  Get dirty easily, so I have to Mr. Clean them frequently.  So, you should be aware then, that they will not stay a nice, clean white, which may be obvious.  WIth improvement, would be a great plastic.  Use softer plastic (check out similar looking shoes in Singapore and see what they use) and get rid of those silly, little bumps on the insole.
