I own several other pairs of Allen Edmonds - Park Avenues in 11D, Kenwoods in 11D, Meranos in 11D. All fit very well (though the Park Avenues are a tiny bit tight). After reading the reviews here, I ordered the Walden in 11E.

Even an 11E is too tight for me. I'm not sure how the sizing works on these, but it's not right. Would highly recommend trying them on somewhere before purchasing them.
