They fit great and I wore them all day at work, on my fit and never had any problems. Nach den guten Erfahren anderer Nutzer, überlege ich fast noch mal einen zu bestellen. As a result, there is no way to get a good snug fit in bare feet on these and even with Nike Athletic socks they are not ever as snug as they should be. If you go off the size chart & messurements make sure you go up a size if your kids foot can handle a whole size up. The fit is good but notice the left foot strings have to be even or somehow my foot sits wrong and aches. Fast shipping great quality ?? The best part is they have a nice thick sole with great support! I love the quality of construction, the breathability of the fabric and I dont overheat at night. Bought for my grandson who is 5. It lasted 3 months and they are zero help.
