The Keiko Mules, open-toe slide from Sempre Di is bold in color and design, with a rich red upper in soft suede, and a multi-colored heel in chevron pattern. The stable block-style heel is a cool 6cm, not too low, not too high. A padded leather sock welcomes your foot and keeps you comfy hour after hour. Open toes, open heels...Spring and Summer beckon. The Keiko shoe is begging for jeans, shorts and dresses of all styles...she doesn't discriminate, she's versatile-but-brave.
