In 1839, Charles Goodyear invented vulcanized rubber technology, and around the same time, the Liverpool rubber company DUNLOP manufactured the first vulcanized athletic shoe in history, marking the origin of global sneaker culture. The EQLZ D404 0G model is based on the classic vulcanized shoe design but features comprehensive upgrades in materials and performance. The COMFYZONE cushioning insole maximizes everyday comfort, while the misaligned design with the heel tab at the front continues the EQLZ@street spirit.
