I have never tried the small the chart always has had me at a Medium and they fit perfectly. Hopefully they have not changed anything except the chart as I just ordered 4. The Epic does have a high vamp. Which is perfect for the Dundee's that I have and the others that are coming. The epic in M seems to fit all my #1 last shoes spot on. For some of the 5 last shoes it is a bit high but they are cedar and it takes only a couple of minutes with sandpaper to shape them to custom fit. Cedar is pretty soft wood. At $18 each (4 for $75) they are well worth it IMO and are owned by AE, in fact they are across the street from the AE shoe factory and make the AE trees of course.
I can't speak for the shape of the shoe tree, but wanted to note something about shoe trees like the epic that have the metal knob. If you keep them in while you are polishing your shoes the knob seems to get in the way. I prefer my shoe trees without the knob in those instances. Aesthetically though, I like the look of the knob better.
