K2 Inline Skates
I have skated on K2 skates - the wheels fell apart in about a month. Design flaw in the K2 wheels - at least for adults like me who skate hard and weigh pretty much - K2 kept sending me replacement wheels and they kept falling apart. Other brands of inline skates and skate wheels never had this problem for me
My daughter uses the K2 Adjustable Inline Skate Marlee. She has used them for about 11 years and they work great. She did not have the problem of the wheels falling apart like I did with adult K2 skates. She now skates with wheels in a hi-low setup with the original wheels as the smaller wheels for the setup.
