First of all, let me say that I don't really consider the color of these shoes to be metallic.  They have very little sheen.  But more importantly, they are just not that comfortable to me.  For one thing, my foot kind of slips around inside them.  I must admit that I have a thin foot...not necessarily narrow...just thin from top to bottom.  Second, the top goes right across the first joint (base) of my big toe, in which I have a bone spur, and it is too tight in that spot.  It hurts!  Since this shoe is not leather, it has no give to it.  Right now I have stuffed a large object into the shoe hoping to stretch that part out so it will be a little more comfortable.  So be forewarned, if your foot is thin or narrow, or if you have bone spurs or arthritis in your toes, this shoe may not be for you.  Regarding size, I wear a size 10.5, so I followed the manufacturer suggestion and bought down to a size 10.  That part worked perfectly.  I can say, if you wear a half-size, don't be afraid to buy down to the next whole size.  Also, I do like the arch support sole.  I hope to get used to them and be able to wear them, but I would probably return them if I didn't have to pay shipping again.  I really wish that Amazon would include free return shipping, especially on such size-sensitive items like shoes.  I probably won't risk buying shoes from Amazon again.

UPDATE:  I changed my rating from 3 stars to 4 stars because once I got the part that goes over the top of my foot stretched out a little, the shoes became very comfortable.  Of course, they still slip a little on my foot, but I have learned how to walk to keep them on.  Also, I have gotten several compliments on the appearance of the shoe.
