"Carbon Free Carlos Bernal: a well deserved Pro skate for someone who has been representing USD for long years and had made is way up right to the top, putting out hammer edits showing amazing skating. The carbon free uses glass-fiber reinforced plastic for the shells base. This construction feels a bit softer than the carbon and offers additional flex and freedom of movement. The trainer like appearance gives you the lowest volume and creates one of the lightest skate on the market. The solid PU cuffs allow the perfect amount of flex, whilst providing sufficient support. The low profile soul plate compliments the overall light weight design whilst still remaining fast and durable on all grinds and slides. The soul plates and cuffs are available in a variety of colors giving you many customization options." -USD
