Aún no los eh probado pero tienen muy buena pinta y en las primeras impresiones se sienten muy bien en los pies además que me encantan que sean de un modelo que no necesitan estar teniendo que atar los cordones

Poor quality control… Received a used pair
Size: 12, Color: Birch Beige/Farro/Ivory, Size: 12, Color: Birch Beige/Farro/Ivory
The shoes that were delivered showed signs of wear. Not sure if this was a used pair or a display pair but this should have been caught from the beginning. I would normally return them, but will be out of the country for the next month and don’t have the time. Unacceptable quality control from the official cole haan store front.
