I did not realize until these were received that there are several holes in the footbed of the sandal. Not sure what the purpose is for the holes, but would not have bought if I had known that. I can see the holes in the shoes on the website photos now that I am looking for them. The footbed also has several ridges in the design that are not very comfortable on a bare foot. Maybe they're for traction if you use them at the beach or pool, but still not very comfortable. I had bought them for a quick shoe to slip on around the house, so will keep them for this winter with heavy shocks.
