It is time to replace my dear, pull-on Ariat Crowne Pros...sigh.

I think the Tredstep Donatellos can work, but I'm a little fuzzy on how the measurements I took translate to the actual boot.

My height is 16.5...the Donatellos are 18". Will they drop too far?

My calves are not the same (too many knee surgeries = one skinnier calf). Left is 14", right is 15+". The Donatello calves are Medium--15" and the Full is 15.75". I don't love a skin tight boot, so which size do I get?
