We get these for our kids every summer.  They are cute, colorful, and wonderful because they put up with everything.  Sand, water, rocks, climbing, running, biking, whatever.  They are great because you can adjust them to fit snugly for rough play outside, yet they can walk in wet areas with grippy soles and no worry about slipping on water.  They dry quickly, ready for the next day.  I cannot recommend these enough, plus, with KEEN you know you are getting a well made shoe.  Don't skimp on kids shoes- their little developing feet need good support from a well made shoe.
