As mentioned in other reviews, take the shoe a size larger than what you normally as it turns slightly smaller.
The only drawbacks:
2 wheels make slightly increased noise while driving
The sticker on the runners were placed somewhat sloppy and are easily damaged but nothing wild.
And I have the feeling that they would have to run a little faster with the built camps, you will easily thwarted. But that is perhaps a matter of opinion. Bin is no longer being driven ^^
Fazi: On the whole, I am for the price [ca. 100] very satisfied and it can only recommend
