Since the Nike Dunk initially launched in 1985, very few modifications have been done to it. Other than the insertion of a padded tongue and a Nike Zoom Air-sole unit in the heel that Nike SB gave it in 2002, most changes have been minor. But with the ten year anniversary of Nike SB approaching, the brand set out to give the shoe a makeover and improve on its lineage: giving it a better gripping outsole; more board feel with better cushioning; improving fit and eliminating pressure points. The Dunk Pro SB will be available January 2011. Check out Autopsy of the Dunk Pro SB below.
