MINIMAL. CAPABLE.
Lyra is a versatile road shoe that combines performance with lasting comfort. Designed with a modern, ergonomic shape and a rounder toe box, it provides a natural, supportive fit—ideal for endurance rides and everyday training. The engineered mesh upper boosts ventilation and highlights Lyra’s clean, minimalist aesthetic, delivering a sleek silhouette with purpose. Its design and construction take inspiration from our top-tier models, bringing pro-level DNA into a refined, all-round road companion.
A NATURAL, NEW SHAPE
Over the past few years, bike geometry and body position have changed a lot. For this reason, the contact points between riders and their bikes have had to evolve accordingly.
Lyra responds to this shift with an updated anatomical shape—one with a straighter axis and reduced drop to deliver a more natural feeling while pedaling.
Lyra’s expanded toe box provides more room and allows the foot to fully stretch, delivering an ergonomic fit and improving comfort during high-intensity rides and on challenging climbs.
RESPONSIVE, EFFICIENT PEDALING
Built for efficiency, Lyra’s fiber composite outsole delivers high stiffness for powerful, responsive pedaling. A reduced heel-to-toe drop encourages a more natural foot position, enhancing both comfort and support. Strategically placed vents improve airflow, keeping your feet cool. The result is a well-balanced platform that maximizes power transfer while maintaining comfort.
PERFORMANCE FIT, ALL-DAY COMFORT
Lyra features a Dual-Dial Li2 BOA® Fit System, offering independent adjustment at the instep and midfoot for a fully personalized fit. The soft, breathable upper mesh enhances airflow across the foot, while strategically placed PU-laminated zones around the closure system and medial area provide added structure and support—ensuring a secure, stable feeling for all-day comfort and performance on long road rides.

Size guide
Fizik shoes
Fit tip If you measure between two lengths or like a little extra room for thick socks, go up to the next size.
How to measure
Stand on a sheet of paper with your heel against a wall, mark the tip of your longest toe and measure from the wall to the mark in mm. Do both feet and use the longer one. Find that length in the table and take the EU size shown; Fizik shoes are sized in EU, so this is the number to order. If you measure between two lengths or like a little extra room for thick socks, go up to the next size. Road shoes should hold the heel firmly with the toes just clear of the end.
