Unveiled for the first time in 2017, the adidas Crazy Explosive Primeknit features a lightweight upper with a sock-like ankle collar, TPU overlays, and adidas branding on the heel. The 'Grey Yellow' version showcases a predominantly grey silhouette with a minimalist Three-Stripes design adorning the lower ankle, complemented by yellow accents on the lace loops and a full-length Boost midsole.
