The folks over at adidas recently teamed up with Solebox and Hypebeast to create two new colorways of the Zeitfrei, an all-new cycling-inspired sneaker. The first colorway, created by Solebox, features a black perforated suede upper with red accents and a white vulcanized sole, while the pair designed by Hypebeast hosts a grey suede upper with yellow and white accents. Each sneaker yields the name of the collaborator on the front of the tongue and a laser-etched number on the inner tongue to denote the shoe’s particular place among the 100 total pairs produced. The Solebox x adidas Zeitfrei will release on May 23, while the Hypebeast pair will drop on May 29. Only 50 pairs of each colorway will be available for retail while another 50 pairs will be sent to friends and family.
