Follow these steps to shape the protectors:
Place the protectors on baking paper and use a blow dryer for approximately 1-3 minutes.
Carefully pick them up while they are warm (not hot) and place them on your shin.
Gently press the protectors to conform to the shape of your shin.
Allow the protectors to cool down on your shin. Once they feel cool, remove them and let them sit for 10-15 minutes to set into the desired shape.
Repeat the same process with the other protector.
