I have a thin heel and thus Scarpa's boots tend to not fit well. With the intuition liners it's hard to tell whether they'd fit after being heat molded. BD boots tend to fit better on me, but that's just because of my thin heel. I have a hard time wearing ballet flats because they slip right off, and these boots had a lot of wiggle room. So, I'm going to return them and probably go with BD. Nice lightweight boots, but poor fit for me.
