Ok, here's my update:
They seem like nice boots, but I'll never know, because they don't fit.
I ordered my size, regular calf, which is what I tried on in at least 2 other brands at the local tack shop. I even had my foot measured and 7.5 medium height, medium calf is for sure my size. No other size will work on me. My boots arrived today and I can't even zip up the back. It's like they were mislabeled by the company and should have been size 7.5 slim or size 7 wide. And it sucks because the eBay
seller doesn't accept returns.
