Let me start by saying, I love Rainbow sandals.  I can wear them all day and they give me the support I need.  Rainbows are also some of the best made and durable sandals I have ever bought.  I guess that is why both my now adult children lived in them throughout their college years. This being said, I was a little disappointed with my most recent purchase. The fit is very snug and requires more work (no just sliding your foot into this sandal!) to put the left sandal on (not the right one though). This is my forth pair and I am not sure if any of the other pairs were as snug when first bought. Those sandals are all still being worn and are at least 5 years old, just different colors.  I love the way the sandals form to your feet as you wear them, so I am hoping the left one loosens up a little.  I am also not sure if ordering a medium size instead of my regular 7 is why this fit is so tight. Would I buy another pair or recommend Rainbow sandals?  Absolutely !  They are the best sandals money can buy.
