Abstract: A shield kit for projectile protection and associated systems and methods. A portable shield kit is disclosed including a flexible shield configured to be fastened to a bar armor frame which is maintained a predetermined standoff distance from a structure, such as a vehicle. The shield kit can be deployed in the field to cover a portion of the vehicle. The shield is configured to prevent a projectile, such as a shaped charge, from detonating as designed.

Abstract: A shoe comprising a sole, an upper, and at least one spring. The sole includes a portion for supporting the ball of the foot of a user. The upper is secured to the sole and covers the foot of the user when the user is wearing the shoe. The upper includes a portion extending up above the ankle of the user when the user is wearing the shoe. The sole and upper are moveable between a plantarflexion position and a dorsiflexion position. The spring is secured to the upper for biasing the upper in the plantarflexion position. The spring is loaded and energy stored therein as the upper is moved toward the dorsiflexion position whereby the spring urges the upper back toward the plantarflexion position.
