I used to own 2 pairs of these - they were my summer faves.  I just went into my closet to pull them out for this summer - and they were gone.  I must have donated them or something.  So, here I am,  buying more of them.  I love the way they feel.  They support my arches way better than most flip-flops.

Their sizing is a little weird - here's what another shoe website suggests - if you wear a women's 5-5.5 order a 5/6.  If you wear a 6-6.5 order a 7.  If you wear 7-7.5 order an 8.  If you wear a 8-8.5 order a 9, and if you wear 9-9.5 order a 10.  One of my old pairs was a TAD too small b/c I didn't know about the size - but for this pair I ordered a 10 (I usually wear 9-9.5).

I love these, and highly recommend them.  Although, I know not everyone's feet are the same so I understand others may not like them, but I love them.  (Also, they are great for walking around in water at the beach or a lake b/c the water goes right through the holes and does not weigh down your shoe.)
