I played 3 hrs of pick up ball in Vibrams. Big mistake but not from heal striking. I burned a big hole on the base of my foot between great and second toe from pivoting. I had been training in them for a few years prior so my legs and ankles were fine. I believe if I had toe socks on it would have prevented the terrible blister. Thanks for the tips about the Kobes, and UA. I will look into those. I have gone back to Adidas but keep damaging my big toe nail from them and I am not certain why.
