So far so good! I hope mine are real after reading a few I got fakes reviews.
Last year I ordered a pair of salt water sandals from Nordstrom, and I LOVED THEM. I took them to Portland Oregon and was in rivers, the ocean, and all over the city.  Then my dog chewed them up when summer was over:(
This year I paid about the same price but ordered them on Amazon to get them quickly.
I wear a womens 9, I ordered a 7 like last year.  When you get them, they will seem way too tight.  Salt water sandals (in my box from last year, it actually included instructions, my amazon box didnt) actually recommends you soak the shoe in water, then put them on your feet and buckle them.  Walk around until they dry - the leather will stretch and custom fit you or your childs feet perfectly.  I just ran my pair under the tub faucet for a minute and slide them on. It totally changes the way they fit, so try that before returning
