I have had several pairs of other Saucony Excursion shoes in the same size including the TR11, TR12 and TR13 which fit perfectly. I bought a pair of TR15s in my normal size and they were too wide. They didn't have a "W" on them, although I suspect they were actually "wide" shoes. I then went back and bought a pair of Excursion 14s which fit as expected.
