I am shocked! With me it is to the point of talking on my Iphone at my ear doesnt feel correct any longer. The difference was not huge, but it was there. This is just a standDo not buy The material looks very cheap, I would have never paid more than $10 if I were to have first seen it in person. I have a pair of Reefs now that are so much more comfortable than these. I heard so many good things about Birkenstock and am disappointed with the defective sandals. Bought and installed this towel rack about a month ago. I cant slide them on, theyre kind of sticky. They actually look very nice!
