Vulcanization refers to a specific curing process of rubber involving high heat and the addition of sulfur or other equivalent curatives. It is a chemical process in which polymer molecules are linked to other polymer molecules by atomic bridges composed of sulfur atoms or carbon to carbon bonds.
Vulcanized soles are very popular for skate shoes as the vulcanization of the sole helps to make soles more resistant to impact and offer more comfort to the wearer. Supra Skytops and Vaiders are just two examples of shoes with vulcanized soles; along with the upcoming Nike Auto Flight.
Those Auto Flights are a tragedy :(
