I haven't skated them but I tried them on and they feel stiffer and cheaper than the currently available dunks. The new ínsole is gimmicky is not really better than the traditional ínsole. They are also a bit tighter, nothing crazy but you feel it. For me the iw dunk doesn't feel like an improvement, just an alternative to the other dunk, nothing i could justify paying 10 dollars more. That being said nike marketing is everywhere, and they really make you feel the shoe is revolutionnary. If they were The same price I'd buy The dunk over the IW dunk.
Just my opinion
