I love these. They run a bit small.  I normally wear a 10. I have tons of sketchers empire in 10s and the material is knit.  The criss cross material on top does not stretch one bit. Not.  One.  Bit.  If you have wide feet order a size up. But get them because they are awesome and very comfortable.  I'm ordering 2 more pairs but I'm going to get an 11.
