Released in May 2019, the adidas AlphaEdge 4D sneaker in 'Core Black' showcased significant enhancements to its upper and outsole. Unlike its predecessor, this rendition featured a Primeknit upper fortified with plastic elements, resulting in improved stability and structure. The lattice-style midsole, crafted through a Carbon Digital Light Synthesis process, offered a responsive sensation with its 3D printed design. Moreover, this shoe's outsole featured Continental Rubber, which boasted a versatile and high-traction tread pattern for enhanced flexibility and grip.
