Nike continues to push the envelope by re-inventing the term hybrid with the Nike ACG Considered Convertible Dunk seen above. The Convertible Dunk features a unique design in which a flap downs down at the back of the shoe which makees it easy to take off.
It is pretty impressive to see Nike trying something new and trying to create new types of shoes which benefit consumers. The Convertible Dunk has been said to be more comfortable than the previously designed Dunks, but nothing is certain. No word on an official release dat yet and may or may not go into production, however it is an interesting idea. Via Sneakerfreaker.
