First it was Nike, now adidas -- retrofitting a classic indoor soccer trainer for fixed gear use. They trimmed down the Samba a little bit, reinforced the toes with some tougher materials, and added some bike-specific graphics to the tongue, imploring the wearer to "slam the hammer down!" No word on availability yet, but we're guessing they'll be more readily available than the Hypebeast x adidas Zeitfrei pack. [Via Sneaker Freaker]
