Shoes are one year old. The midsoles are medially compressed.
When a proprioceptive insole is used in these shoes, the proprioceptive stimulation is distorted (e.g., increased foot twist).

Unstable Shoes can distort the proprioceptive stimulation, which in turn, can increase the foot twist (See Animation Below)
