Review on KEEN Howser Quilted Waterproof Capulet Boys' Shoes in Boots by Francis Vasquez

We ordered these shoes as waterproof fall/transitional shoes for our three year old. Unfortunately, these are the double sizes 25/26 and 27/28. The shoes run small overall, which is why we tried on both sizes. Our son is usually size 26. Unfortunately, these shoes don't fit him because of the double sizes - some are too small, others too big. Why are there no single sizes? It's a shame, because these boots convince us at first glance and would probably be great as everyday shoes.
