Hi I am the test pilot of booster blades. I am a rollerblader usually – although I havn’t skated for years, I was able to adapt to booster blades within a few hours (although I’m not up to trick standard yet) The picture and video that you have is very old Booster Blades have evolved since then! I will gladly send you some newer images and video if you let me know how. Also in reply to the hight question, the booster blades are a little bit (but not much higher) than normal blades. When I have skated on them I havn’t really noticed:)

I am much too fat and not agile enough to use these skates without killing myself.
