I've learned that AK pumps run a half-size large for me, so I sized down to a 7.5 for these. They're a great pump with a modest, stable heel and a sleek almond toe. I like how the bottom isn't completely smooth so I don't have to worry about faceplanting in the middle of a hallway. The footbed is lightly padded, so my heel-hating self can stand & walk in them for hours without complaint. I'll definitely be buying these again, maybe in different colors.
