Adidas x 424 x Arsenal F.C. Ultraboost 21Black & Scarlet
HK$1,609 HK$1,025
Description
adidas continues its relationship with LA-based 424 this season, but brings another partner, Arsenal, on board, too. They all combine to create this pared-back, tech-filled take on the latest Ultraboost 21. It’s all black, save for the hits of vibrant scarlet red — the signature colour of both 424 and The Gunners — and has all the features you’d expect from an adidas runner. Sock-like Primeknit uppers and reworked boost™ cushioning combine for all-day comfort, while a larger Torsion system provides mile-after-mile stability.
