First it would have Fangs in front- Like a P-51 fighter plane of good old WW2 vintage.
Then a long red tongue in the middle...Like the Rolling Stones.
Shoelaces made to look like chains...rusty chains.
Maybe something that looks like a flipped bird at the back of shoe...tell's the other guy you left him far behind.
In any color you want as long as its black.
I got lots more ideas. Some,good.
How about this? When you score,yer shoes light up?..huh..computer chip hooked up to the NBA score machine= my idea works.
Maybe the soles light up in LED's and spell "In yer face!"..that would be sporting fun.
