The heel boot simply slips...
The heel boot simply slips over the driver's shoe. Many companies have also offered shoes with heat protection built into the heel, but these boots provide protection without distraction. Heel boots gained notoriety when Tony Stewart threw his at Kenny Irwin after an on-track incident in a Winston Cup race a few years ago.
Level 7: Heel Boots
One of the first places most teams begin shielding a driver or a component is the last place they should look. The use of body or component shielding is popular because it is thought to attack the problem at the source of the complaint. A driver suffering burns or the failure of a component gets attention, but the root of the problem should be addressed. Doing this will reduce, if not eliminate, the need for extra shielding at the body or individual components in most cases.
That said, there will always be a place for heel boots and other component protective shielding. Fuel pump covers and reflective sleeves for fuel lines have grown in popularity and will always find their place in the industry.
System Concept Through each of the previous sections, we have tried to describe the system concept of thermal shielding. It is important to first look at the source of heat anytime you try to shield or redirect heat. Next, determine if it's a source that can be shielded in such a way to contain the heat (i.e., exhaust pipe) or a source that is required to expel its heat (i.e., radiator). From that determination, you then look at what is to be protected (such as a driver, fuel line, or carburetor). Once you have identified the source and the pro-tected item, an effective plan can be devised to protect the driver or components. The system used may be made of many parts, which is better than relying on only one method of protection.
Thermal protection is highly important in motorsports. Many companies have spent time researching different methods and techniques to shield heat in a race car. It is important to utilize the resources of these companies and the products they designed in order to thermally shield your race car.
