My son wears a 6T to 6.5T and the description said the shoes are about a full size off, to go bigger. So I got an 8 and they fit. They are great looking shoes and he loooves them, they are fun, for sure.  The quality is great as far as I saw, thick canvas, nice color, solid heel. The only thing I noticed is one of the air bladders in the show that puffs the air through the squeaker was harder to deactivate when I tried them it with my hand. Think of a whoopie cushion that goes back to full capacity, versus one that only fills back half way. Ultimately, when my son tried them, they both work and sound the same so we kept them.  I will actually be ordering more.  They send extra squeakers too.
