Adidas UltraBoost 19 'Refract'
The adidas UltraBoost 19 'Refract' sneaker, released in January 2019, is the fifth edition of the pioneering UltraBoost series. This 2019 version ditches the standard UltraBoost design, opting instead for upgrades like a translucent caging system and a thin, yet durable Primeknit 360 upper, constructed with motion weave technology. Its foundation includes the silhouette’s signature Boost cushioning.
