Fizik categorises the Lyra as an all-round road cycling shoe for training and racing. The fibre composite outsole achieves a stiffness of 8 on the manufacturer's own scale, which corresponds to a medium stiffness. The Dual-Dial Li2 BOA Fit System allows separate adjustments for the instep and midfoot. Including the insole, a pair in the medium size weighs around 560 grams according to Fizik.
The mesh upper is vapour permeable. PU-laminated reinforcements are located around the fastening system and on the side. These zones are designed to provide structure and stability. The Dual-Dial Li2 BOA Fit System works with two independent twist fasteners. The instep and midfoot can be adjusted separately.
With the Lyra, Fizik is responding to changes in rider position in road cycling. The toe box is wider than on previous models. The foot can expand fully. The anatomical shape features a straighter axis and a reduced heel-to-toe drop. This design is intended to provide a more natural pedalling feel. The fit is specified as all-round.
The fibre composite outsole uses fibre-reinforced material for power transmission. The reduced heel-to-toe drop positions the foot flatter. Ventilation openings in the sole are designed to increase airflow. The shoe is designed for clipless road bike pedals. The stiffness of 8 places the Lyra in the upper midfield of the Fizik range.
The Lyra is available in sizes 36 to 48; sizes 37 to 47 are also available in half sizes. Fizik offers three colour combinations: Lavender-Mint Green, Coal Black-Black and White-White. The design is based on the design language of Fizik road cycling shoes. The area of use is specified as Road Cycling.
