adidas reinvents the AlphaEdge 4D with reflective functionality for safe running after dark. Launched in November 2019, this Core Black edition's Primeknit upper is given a light-catching underlay, dynamic lacing and stability clips flanking the heel. Three-Stripes branding is found on the tongue pull. The sneaker offers snappy return with a digitally printed midsole on top of a Continental Rubber outsole.
