Birkenstock Arizona Soft footbed Velvet Gray Size 38N

The only reason I can't list these as new is that I tried them on and walked around the house for a few minutes. They fit great - size 38N fits Women's 7.5 M - and are super comfortable. I was trying to make myself like the color, but it wasn't what I wanted. There is a lighter gray but this one is almost black. Lovely color and great shoes, but not for me. They are in perfect condition and were bought directly from Birkenstock, so no question of authenticity. I'm hoping to get a good price for them, so I can buy the lighter gray ones.
