The shoes fit a tad smaller than I expected for size 13.  I've had this experience all my adult life wearing some shoes in a 12.  The manufacturers differ and their shoe sizes differ.  With this said, I am quite pleased so far.  The width of these shoes is perfect.  I purchased these for our trip to Hawaii next month as we expect to be doing a lot of walking.  I will not wear these shoes on the plane however, as they are probably too large or at least a tight fit, under the seat that will be in front of me.  I love Skechers shoes and I have three other pair; all of which are more comfortable than any other shoes I have owned.
