all my respect to akim! this is truely mindboggling. the no shoes thing isn't an issue whatsoever - if you've ever thought about it at all you would have realised that the advantages no shoes gives you easily balances out with difficulties (the lack of grip etc)
the only issue is the ball which is pretty small, but i do believe he could probably do it with a size 5.
there are loads of additional things to point out to do with his physique etc which seem to benefit him with tricks like ahmatw/skatw; without taking away from how incredible this is!
AMAAAZING!
