These flip flops SHRINK if left outside in the sun... I left them on my porch for just over an hour and they curled up and are now at least 1-2 sizes smaller and curled.  This is the second pair this has happened to me with.  I do not recommend them as you often are in the sun when using these and leaving them off for any given amount of time is inevitable.  Teva is normally a great brand, just not the right material to make flip flops with.
