Nike isn't just about paying the biggest superstars to endorse their shoes.  Sometimes they find an amazing leaper like 'Jus Fly' who can pull the cartwheel, between the legs dunk!

Nike is actually launching an online dunk competition starting in July to promote their new shoes 'Hyperdunk+'.

When they drop this Friday (June 29th) they will be able to provide instant feedback to your iPhone about your vert, quickness and hustle.
