The END. x Onitsuka Tiger Colorado 85 ”Bluebird” is a few days from release, and here we get a closer look at this unique offering. The tonal colorway draws inspiration from the shoe’s namesake state of Colorado, which is home to three species of bluebird whose blue hue is created when pockets of air in their feathers transforms light as it hits them, only letting blue light escape. Finishing details include blue tinted 3M panels, customized rope laces and a single feather print at the heel. The END. x Onitsuka Tiger Colorado 85 ‘Bluebird’ lands online at END. on Saturday March 7.
