Bought for my 6 y/o, and these were pretty much the only adjustable in line skates which started at uk size 1. From what I have seen of adjustable skates they are often flimsy, and very bulky. These are the opposite. I followed the instructions and gave everything a little tighten with the included alan wrench, and they feel like they will really last - a lot better than I expected. They fit well, and seem sturdy, durable, and well made.
These were, hands down her favourite christmas present this year, and she absolutely loves them. I too am far more impressed with the overall quality and robust feeling these skates have, than I expected to be. Would definitely recommend them to others.
