I became curious about Aquatalia's Unity boots (now $316-$400) after receiving multiple messages from readers who claimed success with these boots. When my size became available, I took the bait quickly. As soon as I tried them on, I understood the hype. They are the best narrow-calf riding boots I've come across and they may be the best narrow calf boots I've tried on, period.
My size 6 had a 12.5" calf circumference (approximately). This seems to be the perfect size for my 12" calves and I think that anything smaller would be uncomfortably snug. The shaft height was 14.75". The boots are lined with a soft plaid fabric and have a sturdy and comfortable rubber sole. They fit true to size and are mostly leather, with two panels of fabric at the back. One thing I really like is that the fabric panels are very stiff and are rounded so they create the illusion of a fuller and more proportional calf. You can see this in the first two pictures below. I'm wearing tights in the pictures and did not try on the boots with jeans.
