sdandrea1 The plus soles were all different from the earlier Eye2. They were scalloped so the middles were a bit thinner, pushing more weight to the heel and toe.
And as Steve said, they can actually be bent. I've done a few of them. I have to push like hell to move them, but they actually can be moved quite a long way. I bought a cheap 6i to practice on first, and I bent it 3 or 4 flat and then the same up, and then back to standard.
