Very flat footbed but that wasn't the deal breaker since I put in my own insoles. The heel slid up and down no matter how tight I tied them. It only gets worse with something like this, so back they went. I noticed at least one other review stating this issue as well, which made me mindful of it when I tried them on. Also toe box is a little low profile for my big toes but was wide enough. I have had other NB shoes that fit better.
