First, let me tell you what we like about this shoe.  So far, THE COLOR (my grandson LOVES the blue and yellow).  The durability of the shoe is not as good as N.B. shoes we've purchased in the past. We could get past that, however, the Sizing was wrong, wrong, wrong.
My grandson was wearing a size 10 and his toe was almost at the end.  So, I ordered a 10.5 W.  When the shoe arrived, it was smaller in length than his old size 10.  I reordered a size 11 W, this should be perfect.  Not so, fit the same as his old size 10's.  Not enough room to allow Any growth, certainly not a thumbs width at end.
I looked on the 2nd box and realized that, somehow, we were being sent European sizes.  The box said 10.5 W European, 11 W USA. I believe that the shoes that were sent were 10 W and 10.5 respectively. That explained the why the first pair 10.5 W (even though I ordered up a half-size) were actually shorter than his old size 10.  We kept the second pair because his parents were taking him on vacation and there wasn't enough time to reorder. Amazon has a great return policy (first time I have had to return any item).  However, I was charged a return shipping fee because I didn't discover the error until the second pair arrived.  I listed the reason for the return as wrong size thinking my G.S. and his feet had really grown more than I had realized!  Second pair of shoes ordered proved that not to be the case. I now wonder if that was the reason for the deep discount on the shoes?  Hope not!
