The ECCO GRUUV sneakers are specially engineered to provide a comfortable walking experience and support your every step. With the ECCO GRUUV, we wanted to design premium, long-lasting footwear to meet your on-the-go needs. A standout feature of these comfortable walking sneakers is the innovative two-way flex rubber sole that moves and flexes for effortless foot movement no matter the surface. There are also removable dual-fit, comfort-foam insoles for extra width if needed.
