I bought the Natural Multi synthetic, love the red detail.  I can't complain about the price.  I'm a 7 1/2 and that's what I ordered, they are a bit snug but not enough to go up a size.  I'm hoping they will, stretch but with them not being leather I'm doubtful.  They look like leather to the eye but the feel is not as soft.  Pretty shoe, I'm keeping it, wearing it and hoping it will stretch a bit.
