Bauer Supreme One100 Holder: Lightspeed 2 Runner: black edge Sharpening: Shallow hollow Compatible with oven fitting I believe it was a model from around 2012 or 2013. It was Bauer's first carbon fiber boot, and was the top model in the Supreme junior size at the time. The original runner was Lightspeed 2.1 power, but it has been replaced with black edge. It has not been used for hockey. For advanced players. Beginners and intermediate players may not be able to use it effectively. *It is not always the case that the top model is the easiest to skate on. Choosing skates that fit your own skeletal structure is important.
