Significant differences in quality for discounters characterize these inline skates. what else I would not have expected at the price difference. Were the first liner in the class to the 25, I have now grasped a little deeper into their pockets and invest in the K2. A good buy! Looks great, hook and loop fasteners which act-quality and higher-quality ABEC-rollers. Resizing simple. On top of one of this pair another set saver worth 15. The bottom line is a good buy.
