Ordered these for both my kids and we personally found they ran a little large compared with the Asics they had previously. My daughter originally ordered a 6 but they were huge and she end up with a Youth 5 (return process was very easy and happy to say the youth sizes are just as good of quality as the adult sizes). Ordered a 12 and a 13 for my son during the Black Friday Sale based on my daughter’s sizing experience. The 12’s were the right fit for now but he loves the shoes so much we are keeping the 13 for when he needs the next size! They both have said the sole is very flexible and the grip on the mat was great from the first wear.

I have to send mine back, be aware that they run slightly smaller. I typically wear 8.5 in adidas and asics but these shoes might be a hair more narrow so the fit much tighter. The shoe itself looks awesome, even the packing is awesome.
