These are cute and very comfortable shoes, but the large holes in the bottom suck up small rocks and sand that sit in the liner of the shoe.  These may be okay to wear in a creek with large rocks, but not in sand.  I wore them once in the Galapagos, then left them in the shower for the rest of the trip (trying to wash out the rocks and sand)  We live on the coast with sandy beaches, so I will not be wearing them during water activities.  They just such up sand and it fills the footbed, making the shoes heaving and uncomfortable.  Once I get all the rocks and sand out, I will wear them as yard shoes (they are comfortable without sand and rocks in them).
