FINALLY got to try some new Salomons in person at our local REI (don't worry, no intention of buying from them due to their anti 2A stance).
For reference, I have Fred Flintstone feed and wear a 8.5 to 9EE in Danner Acadias, and a 8.5D in Danner Mountain 600 (nice roomy toebox in the 600).
Tried on the XA Pro 3D (shoe, not the mid) in 8.5EE, 9EE, and 9.5EE. The 9EE was the sweet spot once it was on.
Salesman said the EE is a very recent development in the XA Pro line. Doesn't look like the wide is available in the mid-height.
If they ever do, then I'm buying a set from Nelson Uniform (the godfather!).
