2014 has hipped quite a few folks to the adidas Stan Smith, but how many of those have decided to go even deeper into the adidas Originals retro catalog? Do your homework and you’ll also find that the adidas Rod Laver is a critical model from the brand’s signature tennis offerings, one that ignores your typical Three Stripes branding in favor of a Trefoil logo hit on the back side. Check out the shoes below and grab these classics for yourself straight from Packer Shoes in a couple of OG colorways if your rotation is missing them.
