Dude, you've posted the same question on several boxing forums! Good to know we are on the same places...
I just happen to have that very same nike shoes (mine are called SpeedSweep though). They are very light and tight, I love them! They got good grip as well. I tried those plus a few other by adidas at the store, and the nikes are the ones that felt most confortable and tight, so i would recomend them.
Best thing though would be to try any shoes on first, which is tricky if you're buying online...
