Smittie, I'm not sure. Here's the issue....Blondos are sometimes not a great fit on me. I really feel like I need a boot like the Blondo for hacking around...and maybe don't strictly need the Aquatalia.
But tall boots that work for me are a HEWI and I have been wanting a flat riding style boot. My current black boots have a 2 inch heel and are snug at the ankle so a different style. It's a great style, and I love it -- it works for wearing with skirts and cropped pants -- but it's not as good with tucked in slim pants.
Ideally, I'd be trying both on and comparing before ordering up a storm. I'm in TO briefly next week and hope to see something in person.
