Canadian abstract artist, Callen Schaub, just launched his first ever collaboration with Saucony. Releasing two pairs on May 6th, today I’m reviewing one of the two – the Shadow 6000. Taking the 1991 retro runner, this colourway is crafted using smooth white leather and black mesh and suede. However it infuses Schaub’s artwork onto the side panels for an overall muted but still unique look. Huge thanks to Saucony Canada for sending over these!
