This is my first bad review on Amazon, and I almost didn't write it, because I really like Rainbow, but these sandals are so garbage, that I felt compelled. I got them to be able to get them wet, because getting my leather Rainbows wet, especially in salt water, just ain't so great for them in the long run. First impression : they fit much smaller than my leather Rainbows. They strap is immensely tight, and I do t foresee much give, as its synthetic material. I got them wet to see if the strap would give a bit and, much to my disappointment, these sandals are terrible when wet. I've walked on ice with more traction than these things offer with a bit of water on them. My feet slid around so badly, I had to take them off to walk up the hill to get back into the house from the garden. Unreal. Stay away from these.
