Horrible design! Unless you have tiny ankles and ginormous calves, these boots will do you no favors. As a matter of fact, if you have small- to normal-sized calves, these things will actually add inches to that region of your leg. Nice, right? I mean, that's exactly what I was looking for... a boot that made my calves look bigger! Here's a bit of advice to Miz Mooz: create a separate boot for people with large calves. As is, instead of a nice, snug, and shapely, leather fit enveloping a normal-sized calf, the Oakley's shaft, comprised of panels held together by straps and velcro (allowing you to increase the circumference if need be), creates an unflattering silhouette that sticks out like a sore thumb where the panels end and add girth to the area. First Miz Mooz purchase. Last Miz Mooz purchase.
