I just got a pair of Landrollers http://www.landroller.com/index.html
These thing are great! I have not mastered the stopping part though. These skates take bumpy and dirt roads on, and it is still very smooth. Today was my second day on them, stayed in the yard. Tomorrow we go out to the front of the house.
I have also been interested in Nordic skating for a full body work out. Has anyone done this before? Does anyone else have Landrollers?
