Put down the scissors and step away from your Ultra Boosts. What once required a DIY project, is now the latest model from adidas in the form of the Ultra Boost Uncaged. adidas has opted to remove the plastic lace cage from it's 2015-16 staple silhouette and instead integrate the laces directly into the Primeknit body of the shoe itself. The Ultra Boost Uncaged will be available in two colors for men (Grey and Core Black) and two colors for women (Grey and Ray Red).
