Have you tried the Terra Plana Vivo Barefoot Evo? It is a like a mix between the Vibrams and a normal running shoe. No cushioning, light, 3 mm sole, but it does not have toes. I do my running in them and normal running shoes because I do not want to run in my Vibrams or barefoot right before the tournament season (tennis) starts.
I’ve heard about the Evos but haven’t tried them. My sister has been looking at Nike Frees. I’m pretty sure my next running shoe purchase will be something minimal like Frees or Evos.
