For people who are being pursued on foot, eg air force pilots downed in enemy territory, today’s invention provides an additional tool for evading capture.
Each aircrew member would carry an extra pair of clip-on soles for his/her footwear.
When being chased, these would be attached quickly as shown and leave tracks indicating that they had gone in the opposite direction.
I’d also suggest incorporating a small scent release device, which would puff out a little smelly material at each step in order to confuse any dogs which were being used to track the wearer. Several different scents might be used, being sprayed in a randomised sequence.
