I bought these sandals on a whim and they were a Gold Box Deal, so I felt like I was getting a good deal (1st pair of Birkenstocks). I wore them for 3 hours the first night & got blisters on the sides of my feet (I only walked 2 blocks). I understand that may happen with new shoes - but the sandals were also uncomfortable. It may just be my feet (OR I may need to break them in). But for $39.99 - I was expecting a bit more.
