Positives:
The Verabreitung is good. The ball bearing is high, so they are really fast.
Also they act not clunky at the foot.
Negatives:
They are really hard.
AND: Do not hold on foot. I tried it with several pairs of sneakers. It pushes me the tip of the foot during latching always upwards, so that it is already difficult enough that you can at all times is it. On top of that, if I then times it stand and wants a little skating, it lifts me back my heel off the skate and I threaten, rauszuschlupfen back. And that's really, really dangerous. After two or three attempts to almost fall (and I'm a really good skater inline, so it is not because I can not skate), I did it then canceled because it was me frankly too dangerous. I feel it is not safe.
It will probably soon also be available in Germany the Accessory Strap, which then also to keep the back foot. Maybe I try it then again, but without holding the skates not, so I'll send them back again.
