Jess, have you tried the Saucony Peregrine or the new Xodus 3.0. The Xodus was re-designed from the ground up and ain't the same aminal as the old 2.0. My foot sounds very similar to yours except it is tall. I think it is worth checking out both models.
The Asics Gel Trail Attack 7 sounds like what you want except the heel drop is too extreme and the sole too thick! However, since the trend is to lower the drop and reduce the sole maybe Asics changing that in the next model. Might be worth checking with them. It seems like this is the time of year for the new models to start showing up.
