Great flexibility in the sole, nice design and materials. Unfortunately, the shoes are too tight for my little guy's feet. Plenty of room in the toe, but the rest of the shoe was too tight. Could barely fit them on him, the strap cut into his ample ankles, and when I got them off him, his feet were criss-crossed with indentations from the straps. He really liked them, though, and wanted to wear them, even though he proclaimed them 'Too small'. (He is a 21 month old that wears a 7 shoe and a 3T in clothes, for anyone else with bigger kids.) Really wanted them to fit!
