Your footwear for the ride in Shotgun must be on your feet, before you can call Shotgun. Since you must be outside to call Shotgun, some people will simply grab their shoes/sandals, jump outside the building, and call Shotgun before putting their shoes on. This has been deemed Gaping, and is not a legal procedure. You must have your shoes on (if you choose to wear any) before you may call Shotgun.
A good note here, when running out the door, is that slip on shoes, sandals, slippers, etc will give you an added advantage if your goal is to maximize your field of view from the front seat.
Not recommended: shoes with lots laces, boots, flippers, knee high boots, or ski boots, as this footwear takes a bit longer to wear correctly.
2.1.1 You must also be wearing all the clothes and holding all the bags you need. You cannot call Shotgun and then return to the building for site of the Deed to collect goods.
2.1.2 If you choose to not wear shoes, you cannot wear shoes at any time on your ride in Shotgun.
2.1.3 If majority of passengers’ change of shoes (50% or more) are stored in the vehicle, you are all deemed to be on a level playing field and Shotgun may be call when the Deed is done and you can see the vehicle.
Example 1: You have just gotten off the shuttle bus from a day of skiing, and you are wearing your ski boots, as is the majority of your party, you may call Shotgun as soon as you can see the vehicle. Once at the vehicle, you can change into your shoes without loosing Shotgun.
Example 2: You are returning from the beach with your group and everyone is wearing sandals, but everyone has a pair of shoes in the car, you may call Shotgun as soon as you can see the vehicle. Once at the vehicle, you can change into your shoes without loosing Shotgun.
