I bought the Costco version, which as another reviewer pointed out,has no ventilation hole on the side. But other than that, they look just like the pair in the picture here. I previously bought similar duck skimmers of a different brand from Amazon. Those were very uncomfortable and I had to return them. Due to that experience, I was skeptical about these type of rubber flats as my feet are very sensitive and sweat easily. When I tried these on at Costco, they seemed to rub my heels a bit. I went ahead and bought them anyway given the low price. And I am very happy with my purchase!!! I wore them out to dinner today after the afternoon thunderstorms. They are very comfortable, even more so than some of my leather and fabric shoes. This is a big surprise to me; I have been having foot pain for over a year due to herniated discs and a lot of the shoes I own are no longer comfortable to walk in as a result of the pain. These skimmers also seem to be broken in easily, as I no longer feel the shoes rubbing my feet. Best of all, my feet are not soaked in sweat as I feared from my experience wearing Crocs. So I guess not all rubber shoes are created equal! The only down side I can think of is that the bottom can be slippery when you walk into a Chinese restaurant with some slightly greasy spots on the floor. I almost slipped a couple of times in these shoes but have never had the same problem in that same restaurant. On the other hand, they are supposed to be worn in the rain and I certainly have no problem walking in them on rain-soaked grass.
