I was looking for a zero-drop shoe and came across the Altra's. They're a step up in terms of protection from vibrams or NB minimus, but still give a natural foot strike.
The roomy toe box is an added plus, especially on trails when you can really feel your feet being able to get traction with the ground.
They run a little small, so order at least a half size up. I typically wear a 12, the 12.
