Heel height: Approx. 3 1/4'' Tall. Gemini is a surprising sandal! Burnished leather is just this beginning of this open-toe slide. Cross-stitch detailing on a cutout upper and a faux cork footbed give texture with a sense of lightness. The upper and matching heel seat provide extra cushioning. The polyurethane outsole gives this 3-1/4'' stacked heel sandal extra comfort and flexibility.
