This adidas AF 1.4 PK features a Scarlet and Shock Purple color combination. Constructed with Primeknit across the uppers and coated overlays while dressed in Scarlet Red. Insulation is added to the liners with a hiking outsole. Completing the look is a suede overlay at the heel done in Shock Purple. At least for the low-top AF 1.4 PK, anyway, as we can see here with a decidedly more vibrant edition than the plain black and white debut version, featuring its water-resistant Primeknit upper in red with a purple suede heel panel and light blue heel tab loop.
