Calling all Lanvin flat boot owners! I really want to buy these boots and am ready to fork over the $860 that they retail for. Before taking the plunge, I'm wondering if I can get some feedback on the boots. Like, measurements would be great (shaft and how tight/loose are they around the calf)? I have tiny calves and am very petite so would these be okay? I've had a hard time finding the right boots that fit, tried Loeffler Randall, Delman, Belle and all to big/high. Would love to hear from anyone on these lovely boots. I'm looking to get them in the black leather. Thanks!
