then looked at this (ignore idiot presenters)
I can only think that Boost with it's east quick compression and return of energy is good for the cadence and footfall of running, but for the runa dn lunge and stamp of tennis I am beginning to think that Boost aint enough, indeed earlier someone mentioned HD Boost is coming...
