New Balance Kids PK888v2 (Little Kid) Grey/Rainbow

Size Kid 10.5 of 888v2is it's about the size as Kid 11 of Rave Run. Also, the regular width of 888v2 is about the same as the wide width of Rave Run. Just what's wrong here? I really wish NB makes a consistent sizing. A half-size on 11-inch feet may not make a big difference, but it does make a huge difference on 5-inch feet of kids. The inconsistent sizing is extremely inconvenient. Basically, we ordered 10.5 of 888v2 and 11 of Rave Run, and we ended up with two pairs of identical size. Other than that, the quality of 888v2 seems better than any kid's shoes we have ordered so far. We love the design and quality. recommended, but watch out - NB sizing is different on different models.
