I have to give the best of props to Speed Art/Sanwei as their Fireflash shoe is amazing.

It looks sick, it feels sick and it performs sick. Before I kept two shoes in my bag, one for wood floor and one for PVC floor. Now I don't need that at all since this shoe works on both and it works amazingly. The grip is outstanding, honestly second to none. Take Mizuno, Butterfly, Asics, they are not even in the same dimension.
The only shoe that is in the same dimension is the Yonex Aureus Z copy from Kawasaki (maybe the original too) but I think even that doesn't match the grip.
This Sanwei/Speed Art shoe has the best grip ever, a hard boost foam midsole, has a carbon plate, it is lightweight, and had BOA lace. I have never seen a more modern shoe for table tennis ever and it is lovely.
But still it's by far, non contested feature is it's sole grip in every situation. This feature alone would make it the best table tennis shoe.
