I love flats because they can be sexy, fun, and comfy at the same time. BUT when I buy flats the sizing matters so much that I'm scared to buy online. If they are half a size too small, they scrunch up my toes in a very very uncomfortable way. And if they are half a size too big, the heel flops off my feet!! ush: Anyone else have this problem?? Is there something I can buy to stuff the tip? I also recently bought a pair of flats which I know is the right size, but for some odd reason the right heel still flops off my right foot after a few steps? WHY?!
