...doesn't fit well with rounded and angled shaped FitFlop. It's very unfortunate because it's so comfy. I also have a super skinny calves (very unusual) so it's too roomy and likes to fall down tiem to time although the leather is stiff and should hold up. Honestly I wish I could wear those boots a lot but because of those issues, I only wear less than I want and yes! I am keeping them!
