The short cuff and flex curve allow the junior racer to efficiently and effectively flex the boot to ensure proper energy transfer. Equipped with a race liner for a more precise feel, the Firebird R 90 SC is supportive and stable for crushing gates at max speeds. Fun is not simply stacking visits to the podium, it’s everything that goes into it along the way. It’s the feeling of nailing your first cross block, seeing the faster line or feeling your best turn of the day.
