Nah...there have clearly been other people in here who've balled in the XIs and think they're built for basketball, not just casual wear.
It's just that the one person who's said these have "Godly traction" was also the dude who said the Dunkman would overtake the Jumpman in 10 years, the Kobe 8 Milk Boas are the cousins of the Jordan VI Carmines, the XIs help him dunk significantly better, etc, etc...
Just like sleep is the cousin of death. Why can't Milks be cousin of Carmines?
The padding in the XI grips your feet with outstanding support. It makes the explosion when you leap up into the air a lot more drastic, thus helping your vertical leap.
When I drive the ball to the rim in the Kobe 8's, it just isn't the same as when I am driving the ball going for a layup in the 11's (hence TRACTION/GRIP-- that's the difference). It makes me FASTER than other people on court. It is what it is, I am just saying that the XI's are beast on court and anyone who tries to argue about it with me I already know must not really be balling in them and just hating. haters gonna hate....
