I just bought a pair this summer (middleburg zip field boots) from Dover, since they were only $200.
My calves got too big for my old boots, so I went out looking for a new pair and I wanted some with an elastic panel all the way down the back. These had the elastic, and were a good price, so I got them. I also read about the foot running big, but bought my usual foot size anyway since my legs are long and I needed the height.
Well, the foot really does run quite big. I have a lot of room between my toe and the tip of the boot, but I walked around in them and decided I could live with that since they were comfortable enough and weren't going to give me blisters. Unfortunately, once they broke in they lost some of the height, so now I think they're too short :( I have freakishly long legs. So, I might have to make these my schooling boots and buy a new pair of a different brand that comes in tall. I knew I was taking a risk with the height when I got them so that's not their fault.
Anyway, I only used them for showing so I didn't wear them enough to say how they hold up to daily wear. I got lots of compliments on the ankles - they have a nice slim, flattering ankle (some boots look bulky in the ankles). One boot did rub me at the back of my ankle for a while til it broke in, since it is so form fitting there. I like the elastic panel and the spanish top, and the laces are elastic so you don't have to worry about tying them. The leather is more dull/less shiny than my old ariats but I didn't mind that. They are nice and grippy too - help my legs stay still.
Edited to add: mine look a little lumpy down the back where the zipper is, though I've noticed a lot of zip tall boots suffer from lumpy zipper syndrome, too, so meh. That part gets turned towards the horse when riding.
Hope this helps!
