Can't figure out why, but Merrell sandals are impossible to find in most stores and yet they are some of the best-made and comfortable sandals on the market.  I had 3 foot surgeries and am not supposed to wear sandals, never mind flip-flops, but these Merrells are absolutely fabulous, very well made with arch support and great support on the side as well (something flip-flops never have).  The number of colors and styles I found through Amazon were amazing, something not found on the Merrell site!  I received my order promptly and am delighted with the sandals.  They may be pricey but are washable and last for years while giving your foot amazing comfort.  I cannot recommend them enough and I have tried many other brands including the Mephisto brand that cost twice as much and is less comfortable.
