The PR (Progressive Rocker) frames are an evolution of our NR (Natural Rocker) frames. Using 5 smaller wheels, the PR frames are designed for a more artistic skating style and skill development on smooth surfaces. Whereas the NR frames (4 larger wheels) work better for versatile skating on all surfaces. Recommended frame length based on boot size: Progressive Rocker frames are available in three different sizes, PR76, PR80, and PR84, to help optimize the skater's experience based on their foot size. All PR frames have a relatively short contact patch and are very maneuverable while still being very easy to balance on because of how long each frame is. The smallest size PR76 is the easiest to maneuver but may feel less stable with larger feet so it's receommended for skates size 7.5US or smallerFor size 7.5-10US skates the PR80 is a great middle ground of maneuverability and stability. It also offers a slightly smoother roll than the PR76 outside.For skaters with feet larger than 10.5US, the PR84 offers the greatest stability and speed. It still has a short contact patch so it's still appropriate for 3-turns and other artistic skate moves. All sizes of Wizard PR Frames fit on all sizes of UFS boots.
