I ordered this for me (small adult female) for an upcoming cruise. I used the size chart and ordered a Big Kids 5 (I had measured wrong, it turns out). They sent a boys 4 and it was way too big.  Since the size said "Big Kid" and not "Boys" I figured they had somehow adjusted the sizes?  So, I sent that back and ordered a Big Kids 4, and they sent a Boys Size 4 again (it was still too big), so I had to send that one back too. According to the size chart, I was between a Little Kid's 3.5 and a Big Kid's 4, but the 4 was way too big.  The quality of the shoe looked really good, but the sizing chart was off. I was not happy about having to send it back twice. Refund was handled quickly on the first return.
