The Boys' Techsun Vent Water Shoe from Columbia likes to do all the things he does, like splashing, stomping, and generally playing in the water. Luckily, it comes with quick-drying, hydrophobic straps with hook-and-loop closures that make it easy for him to get them on and off, and Omni-Grip rubber soles so he can climb rocks, explore tide pools, and excavate mud puddles without slipping.
