With an official release date set for March 20th, the Nike Dunk Low Pro SB “Larry Perkins” has started arriving at the occasional store this week. This shoe, as you may remember, was known as the “chirping bird” Dunk as its hallmark feature was a tongue which chirped when squeezed. That sound has been changed though, to that of a ringing phone. Again, these will be in stores by March 20th.
