I could actually close the V so both ends touch with no gap at all. When I walk I do feel heel lift. I could actually fit like 3 fingers in the side. What bothers me is when I step, my foot pushes down on the side and the ankle bone rubs against the side. I could imagine walking all day and it will make it pretty sore. It doesn't feel as snug as the 7.5 D. Maybe that is the right size for me.
I went to 2 different AE stores to get fitted, 1 in Seattle and 1 in San Francisco. One store measured and fitted me in 7.5 D, the other store fitted me in 7.5 E. Kinda weird how I measure 8 - 8.25 D on 1 brannock, and 8 - 8.25 E on another.
