You should go up a size (I normally wear an 8 & might have ordered the 38 but ordered the 39 after reading the customer reviews). The shoes came packaged very nicely including a draw bag to put the shoes in. They are very comfortable with memory foam. Walked around a hilly town and my feet felt great and it was the first time I wore them. The back won't slip as long as you wear a footie/sock of some type. I ordered the "Jeans" color & love the color.
