CR7 x Air Max 97 'Portugal Patchwork' was a sequel to Cristiano Ronaldo’s 2017 Air Max 97 CR7 ‘Metallic Gold.’ Nicknamed the ‘Portugal Patchwork,’ it features a Portuguese flag-inspired University Red upper with gold and green accents. It also comes with patchwork-like panels as a tribute to his mother stitching his shoes back together when he was a kid.
