|The french mate Canon (not me ;-)) made the protecs with epoxy and carbon fiber, molded on his shoes (with plastic/wax between to not stick). For more details, I ask Canon if he allows me to translate his article for rollerquad.

: from what I can make of it... you make these yourself out of epoxy? and the fun part, you make custom designs! French-English translation, please.
