I love my Ariat Coniston Pro GTX. They are great for riding and just on the yard. Most comfy boots ever. They are expensive though. I only got mine because I managed to get a really good deal.
I'm not riding at the moment as 8 months pregnant so I have bought them home from the yard, cleaned them up and now I am just wearing them out and about. They are so nice!
I really, really like them and didn't take any wearing in at all really. I struggle to find boots that are long enough but slim enough in the calf and these were the only ones of about 10 that I tried on that virtually fit like a glove.
