The key comes with the triple-layered sole, each layer adding its own strength to the mix. Get used to all-day comfort with SensorFlex™'s firm upper layer, and be ready for any terrain with the softer EVA mid-layer, designed to adapt to uneven surfaces.
The bit you see on the outside? That's our grooved outsole, on every SensorFlex™ shoe and crafted to flex with every step. The bottom line is you'll keep walking all day and long into the night, with comfort and style to spare.
