You can have a free pair of Reebok's latest running sneaker as long as you can run fast enough.

A video posted by the sportswear brand yesterday features a cool installation in Stockholm where passersby can run past a speedometer and unlock a pair of shoes if they clock a decent speed.

The video doesn't make it explicit exactly how fast people have to run in order to get the freebie.

The shoe up for grabs in the clip is the Reebok ZPump 2.0, a quiet silhouette that extends Reebok's renewed commitment to Pump tech that began on the ZPump Fusion.
