Apparently invested K2 currently a lot of money in closures as BOA or the used here, in which you just have to pull a 'hook' and shoes sit (relatively) fixed. The only downside (hence only 4 stars) is that the plastic buckle probably does not seem so important at the top in this development. Especially for people with thinner lower legs and big feet (like me) it would be nice if the buckle were the last stop and would closely to close. Unfortunately, she bends to light and you have to watch that you can not produce a breaking point in frequent use, where the buckle then gives up the ghost in the short or long. Should not happen in the price. The rolls are good, just wear out, as noted correctly in the other reviews, quickly. The runnability of the ball bearing is fine. There we touted as further development of APEC-bearing, but acts while driving more like a maximum equivalent replacement. Despite a solid shoe that still brings joy to a few kilometers driving.
