The upward trajectory of Solebox and Saucony collaborations culminates in this upcoming "Grey Devil" colorway of the Shadow 5000, featuring a makeup that clearly expresses the Berlin-based retailer's singular aesthetic. The classically styled runner has a black leather upper with off-white suede forefoot and perforated toebox, with hits of bright purple at the eyestay and lining. Black tonal laces, a true white midsole and gum rubber outsole round out the details. The Solebox x Saucony "Grey Devil" Shadow 5000 is slated to drop sometime in August. Stay tuned for further details.
