Baby / toddler keen knotch hollow sneaker. Size 6. Structurally in excellent condition, they’re just dirty. I haven’t tried cleaning, but they are machine washable! Outside sneakers for outside kids need to check a lot of boxes: Light and flexible, built to stand up to all the play kids jump into, and an easy-on, secure fit (hello, double hook-and-loop straps!). We added one more: machine washable. Our newest play-ready shoe with a rugged, low-profile outsole for 365 days of fun.
