These shoes are so neat for toddler feet. They slip on easily (even over grippy socks!) but stay on well and seem more comfortable than traditional sneaker-like shoes because of how flexible they are and spacious on the inside. Now these are lightweight, if baby is tromping through gravel all day I’m not sure I would choose these, or when it’s cold or wet we gotta go with a different shoe. But for everyday casual wear they are *chefs kiss*.My child wore the “12-15 month” size while fitting in US size 5 toddler shoes, then recently transitioned up to size 6 so I ordered the “18-24 month” size which are a teensy bit big but they are still wearing them with no problems. Also the shoes are adorable I regularly get asked about where I got them.The only issue I had was not with the item but when I ordered the next size up I had to return TWICE because the warehouse sent the wrong size two times in a row. Very frustrating, but I liked them enough to deal with it and order again until receiving the right size. Bummer for the product to be marked as a “frequently returned item” when it is a truly awesome toddler shoe.
