Your 11.5 E size will be comparable to our 11.5 wide sizing, which comes in a variety of our shoes. We even have select models at 11.5 XW. I would focus more on trying on those two sizes than simply going off of a last description.
With that being said, our Contour Last (Contour Series), Nitro Last (D.N.A.) both feature a roomier feel like the Austin last. The Laser Plus last in our DryJoys Tour and Casual will also give you some additional space in the forefoot.
