    Comfy with One Problem

    These sandals are VERY soft and comfortable. When I first started wearing them I absolutely loved them, but after a while, the skin on top of my foot started to become irritated. Turns our that the rubbery tag inside one of the straps was sticking to and rubbing on my foot. I tried to peel it off, with no luck. There is a tag on the other shoe, but it does not irritate the top of my foot like the other one. So, I really can't wear these sandals for very long before my skin gets too irritated to keep them on.
