Originally developed for the military, Oregon Aero ShockBlockers insoles combine state-of-the-art designs and materials to provide shock absorption, flexibility, abrasion resistance and conformability for the foot. Now law enforcement personnel who require foot protection can benefit from using ShockBlockers insoles in boots, cycling shoes, and even athletic and civilian footwear. The ShockBlockers insoles' low-friction fabric helps prevent high temperatures (and blisters). The high-wicking nature of the fabric carries whatever heat is created to the outer edges of the fabric, lowering overall temperature and permitting moisture to evaporate. ShockBlockers insoles are available in both men's and women's sizes and in three styles.
