Part shoe, part sandal--the Merrell Boys' Hydro Choprock Sandal is a complete package perfected for watery hikes like Zion's Narrows. Its mesh upper compliments the quick-drying lining whenever the hike turns dry, and the toggle closure is super simple for children. The cushy EVA footbed feels good whether you're hiking water or not, and M Select Grip ensures traction on wet and dry surfaces.
