Buckles snap and laces knot but the Secure-Fit lace capture system on Keen's Kid's Newport H2 Sandals eliminate the unnecessary frustrations with getting ready to go outside. Keen's Kid's Newport H2 has a special waterproof polyester webbing that's better suited for play around water than other sandals with leather straps. There's also a hydrophobic SBR lining that helps keep the straps from rubbing against damp skin (be sure to size properly). Up front Keen's patented toe bumper protection helps protect young feet from unseen trail obstructions and hidden river rocks. Like Keen's adult-sized footwear Kid's Newport H2 Sandals have supportive metatomical EVA footbeds to optimize comfort. If you live near a beach or your kids just like to hang by your backyard pool these are perfect sandals for throughout the year.
