Last time END. and Reebok collaborated on an Instapump Fury, for 2016’s ‘Pink Salmon’ and 2017’s ‘Black Salmon’ releases, it was river wildlife that inspired them. You have to look much further into the past for this pair’s aesthetic influences. As its name suggests, the ‘Fossil’ takes cues from archaeological dig sites, combining hairy and smooth suedes with a cracked version of the model’s famous inflatable bladder to form the upper. The comfortable Hexalite cushioning in the sole is anything but prehistoric, but the tread certainly is — it’s printed with ammonites for a final geological touch.
