Poor sole design could result in injury to heel.
Size: 11, Color: Grill/Mint Wave
These would be so much better if the sole did not expose the heel to possible punctures. There is an actual cutout of the sole where only the spongy part of the shoe is exposed to the heel. Anything sharp will go right through.

Excelente producto
Size: 8, Color: Black/White
Sandalias muy cómodas para caminar, recomendadas para utilizar en viajes largos y clima cálido. Sugiero comprar una talla adicional, sin embargo siguen siendo muy cómodas.
