The adidas 4DFWD Pulse ‘Black Sonic Ink’ features a lightweight and sustainable build that incorporates at least 50% recycled materials. The seamless upper is constructed from open black mesh with a purple textile underlay. Reflective three-stripes reveal an iridescent finish for added visibility in low-light conditions. Responsive cushioning is provided by a hybrid midsole that combines soft foam and a 3D-printed heel cradle, precisely angled so that it absorbs impact and guides the foot forward with each step. A high-traction purple rubber outsole delivers optimal grip.
