The EXOSpeed II Series is completely non metallic. The molded resin and nylon "speed laces" make adjustment faster as the laces glide smoothly. The inner air mesh lining keeps officer's feet cool, while the medial side ventilation screen increases ventilation and moisture dissipation. The "last shape" is contoured around the heel to avoid slippage - reducing friction and perspiration while improving stability. The EXOSpeed II Series is currently available in 3 styles; 8-inch Black Lace Up, 8-inch Desert Lace Up and 8-inch Sage Lace Up.
