Built with eFlex Technology for lightweight, flexible comfort and arch support, the Kellina is a knit flat that quietly does everything right. The slip-on silhouette features a textured knit upper with a gentle stretch that adapts to your foot, while a subtle pull tab at the heel makes getting in and out effortless. A contrast-stitched trim along the sole adds a refined, tailored finish, and the rounded toe gives your foot plenty of room. It's the kind of shoe that disappears on your foot in the best way possible. Inside, a soft touch footbed and sock lining keep every step cushioned, and the orthotic-friendly construction means you can swap in your own inserts when needed. Available in medium and wide widths.
