So earlier at practice I experimented with flat feet coming off every wall. There was a very noticeable difference. I could surface with ease past the flags, without any DKs. In my first two years of swimming, I have used just the balls (and toes) of my feet in coming off the walls.
Flat feet (that is, both ball and heel) feels a little awkward right now, like any technique change, but I think I'm going to start adjusting to it for permanent use.
Thanks to Jim Thornton who suggested I make this a poll!
I go with the flat feet as much as I can. For me I have ankle pain due to an old sprain, in the right ankle, which is also my stronger leg. The more of the foot I get on the wall, the harder a push I get and the less pain I have. It's an adjustment I've made since the sprain happened almost 3 years ago. If I get too far away and just push off with my toes, the pain can be bad.
