The collaborations never seem to end – but that’s ok, most of the time they add a bit of interest to an otherwise all too boring retail industry. Especially this time. Friend of PSFK Jeff Staple has just announced that he will be designing an exclusive Airwalk collection for Payless. The affordable shoe store has been experimenting successfully with designer collabs in recent years, including putting out twelve original street and skate styles for Airwalk per season. Staples’ line will launch at about 400 Payless stores in Fall ’09, and will retail at $50.
