I had some tevas about two summer's ago, and they weren't very comfortable. Then last summer I bought myself a pair of Birki's 'Caribbean' they are made of EVA. They were only $45. And I love them, I lived in them last summer and plan to this summer. My first pair was yellow, (they are still in excellent shape, I just wanted another pair) and I just ordered a pair in green. They come in black, pink, and green this year.
I love my birkenstocks and I won't wear anything else but. I think I've spoiled myself. I have happy feet!
My feet used to hurt so bad, so my husband suggested that I try Birkenstocks so I ordered a pair and fell in love with them. And now I have 7 pairs.
