I always use my hands to wipe my shoes. Actually, between games, i take my shoe off and stick it in the water tap or fountain, and basically wash the soles. It has become a goodluck charm for me since i do it so much now
There are some anti-static detergent spray you can use on the sole of your shoes that will help. But nothing beats a clean floor.
Soap powder We use soap powder on wooden floors in Malaysia esp. when its dirty /oily... works wonders... gives fantastic grip for whole 2-3 hrs session. Try it! but ensure floor is not wet!
