Great shoes true to size
Size: 11, Color: Ivory/Microchip/Ivory, Size: 11, Color: Ivory/Microchip/Ivory
Great shoes, came with box. Brand new, true to size 11 US ! :) in my country they cost 270 USD so, really nice and very comfortable shoe considering i have plantar fasciitis. 3 month update: They get wrinkles pretty fast in just a few weeks due to the material, it’s not noticeable to others at all, but it’s worth keeping this in mind when buying this particular model.

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.
