These shoes along with the Thorlo L3 have cured my year long battle with the evil foot pain God of Plantar. I guess the CB 2.3 were the culprit all along. Last night I played 3 sets with no pain for the first tme in over a year and was not limping afterwards. The CB 3.3 are simply the best. Anyhoo, here are the souls after 25 hours of play on Newbury Park deco turf and JP Paulsen's indoor hard tru court.
