The adidas 4DFWD Pulse ‘Black Sonic Ink’ is designed with a focus on sustainability and lightweight construction, utilizing a minimum of 50% recycled materials. Its seamless upper is made from black open mesh, complemented by a purple textile underlay. Enhanced visibility in low-light conditions is ensured by reflective three-stripes that provide an iridescent finish. The unique hybrid midsole offers responsive cushioning, incorporating both soft foam and a 3D-printed heel cradle. This innovative design absorbs impact and guides the foot forward with each step. Furthermore, the high-traction purple rubber outsole enhances grip for optimal performance.
