I switched to this method in February, and have been suffering from horrendous blisters ever since. The worst are on the back, inside edge of the ball of my foot, slightly into the arch, which I guess gets more friction when I land on the forefoot. On the left in particular I get a blood blister there after every run, and when it's painful, I think my running style changes, which is aggravating an old knee injury, (N.B.: it got squashed & twisted under a crowd at a gig last summer).
I went to see the podiatrist at Up & Running, Hyde, and he's advised switching back to heel to toe as that's what I do naturally. He thinks most runners will only naturally go up onto their toes when sprinting.
Not sure what to do now - obviously I want to run faster, but any benefits of the POSE method evaporate when I'm compensating for blisters, and I don't want my knee to suffer any more.
