Sweet. There IS hope for the ol' Heels Sinking Into Grass problem.
SoleMates look like a pretty good idea to me. Since I haven't tried them (yet), I can't give you a real review. I CAN tell you they are the only thing I've seen so far that gives me hope that my bridesmaids aren't going to have to wear wedges. And that I'm not going to have to have a damn wooden aisle built over the grass.
