I would give this product full marks for comfort and am also pleased to be able to get a stylish walking sandal in a large size. My only complaint is that the opening clasp is extremely stiff - resulting in a broken finger nail. I am now using the velcro adjuster strap to put on the sandals. I have had various family members try and open the clasp and they have all failed. That aside this is my second pair of Merrell sandals and I will be investing in more in the future.
