The Zest has a two tone knitted upper. The upper has Flexiknit technology that adapts to the shape of your feet for constant support and an uninhibited feel no matter what the movement. The insoles have Ultrahop technology that mimics the movement of your natural stride to provide unencumbered comfort and cushioning. Aside from this, the Zest has unique design elements. Contrast PU panel and branding add a youthful, spunky edge. The barcode printed on the side takes the cake – it adds a vibe that says “cool and unbothered” and heightens the look of the shoe, and your outfit!
