I bought these in 5.5w, the W meaning "wide."  I buy all my son's shoes in this size (at the moment anyway).  We could barely get my sons feet sqeezed into these shoes.  They were long enough, but we couldn't fasten them - not wide enough!

These look really great though, and they are so light!  I wish they fit him.

Leaving this review just so anyone who needs "wide" will know that these will probably not fit.
