My son was measured at Stride Rite as a 9 xw.  I thought it would be wise to order a 1/2 size big so, I purchased the 9 1/2 w in this style and was very excited to receive the shoes in 3 days.  The style is great and will go with everything.  However, the 9 1/2 w is HUGE!  He has at least a full inch between his toe and the end of the shoe and the strap on top was too long to fold over.  I will exchange for a 9m and hope for the best.  Beware, these run long and wide.
