Hi girls, I bought two pairs of Havainas today. I wore one pair around the house today and the right thong kept cutting into my foot. Upon taking the shoe off, I noticed that the right shoe's thong-part was distorted and didn't look like the left one (the sharp edge sort of curled in). I noticed that my other pair of Havaianas is also this way -- the right shoe's thong is curved inward unlike the left's. Has this happened to anyone? I bought both pairs at Urban Outfitters. I don't know what their exchange policy is like -- I cut the tags off but never wore them outdoors.
