I tried going rollerblading today with the new blades and decided to give up after about 35 minutes. Or rather after going for about 15 or 20 minutes i decided to give up and it was about 30 or 35 minutes before i got back to the car.
At first i wasn't sure if i'd gotten out of shape really quickly from not rollerblading for about two weeks and the bearings on the new skates were kind of sucky, or if they bearings were just _really_ sucky. However while heading back i realized that i'd actually coast to a stop on a slight downhill grade unless i actually worked to keep moving. I think on level ground they coasted to a stop after about two or three feet unless i pushed off really hard.
The boot part isn't quite as comfortable as the K2 ones but still a lot better than my 10 year old ones, so it's really just the wheels/bearings that are the problem. I need to try loosening the bolts on the wheels and/or oiling the bearings if that's possible. If that doesn't work maybe i can actually swap out the newish wheels from my 10 year old rollerblades or the ones from the K2 blades if i can't actually get them fixed.
