Instead of trying to keep your little fish out of the water every time you two go out, just slip the Keen Little Boys' Seacamp II CNX Sandal under his foot and let him splash away. Keen utilized its proprietary Keen. CNX technology for lightweight protection that includes a minimal heel-to-toe drop for natural movement, a contoured arch for underfoot support, and minimal upper construction for a comfortable fit and feel. The upper consists of washablepolyester, a hydrophobic mesh lining for breathability, and an Aegis Microbe Shield treatment to eliminate odors, stains, and deterioration. The Secure Fit Lace capture system helps the hook-and-loop strap hug your boy's entire foot instead of uncomfortably pulling at one point. The rubber sole features multi-directional lugs for secure traction over slippery surfaces in the water, and it won't muck up your hardwood floors at home.
