Gaerne G.IRON – Lightweight & Breathable Triathlon Cycling Shoes

The Gaerne G.IRON is a high-performance triathlon cycling shoe designed for athletes seeking the perfect combination of comfort, breathability, and efficient power transfer. Featuring a lightweight construction, quick-adjustment Velcro closure, and the Gaerne EPS Carbon Power Sole 8.0, these triathlon shoes are engineered for fast transitions and reliable performance.

Whether you're competing in sprint, Olympic-distance, or long-distance triathlons, the Gaerne G.IRON delivers outstanding comfort, stability, and efficiency throughout the cycling stage.

G.COMFORT FIT – Anatomical Support and Lasting Comfort

The Gaerne G.IRON features the innovative G.COMFORT FIT, developed using Gaerne's classic anatomical last.

Designed to provide a natural, supportive, and well-balanced fit, this construction ensures excellent foot stability and long-lasting comfort.

The ergonomic design helps maintain a secure and comfortable fit during powerful pedaling efforts, making the G.IRON suitable for both competitive triathlon racing and extended training sessions.

Ultra-Breathable Microfiber Upper – Ideal for Sockless Riding

The lightweight microfiber upper features a minimal-seam construction that reduces friction and irritation, making the Gaerne G.IRON particularly suitable for triathletes who prefer cycling without socks.

Strategically positioned perforations improve airflow, promote efficient water drainage, and allow the shoes to dry quickly.

This breathable construction helps maintain comfort during demanding races, especially when transitioning from swimming to cycling.

Quick-Transition Velcro Closure System

The Gaerne G.IRON closure system is specifically developed for fast and efficient triathlon transitions.

A wide transversal strap securely wraps around a large area of the foot, while an additional lower Velcro strap provides precise adjustment and improved stability.

This practical design allows athletes to put on their cycling shoes quickly and make easy adjustments throughout the race without compromising comfort or performance.

Anti-Slip Heel Cup and Easy Entry Design

The integrated anti-slip heel cup helps keep the foot securely positioned inside the shoe, improving stability and control during powerful pedal strokes.

A convenient rear pull loop allows fast and effortless entry, while a small internal elastic insert helps athletes secure their shoes to the bike for quicker transitions.

These features make the G.IRON an excellent choice for triathletes looking to save valuable time during competitions.

EPS Lightweight Transpirant Insole

The EPS Lightweight Transpirant Insole provides anatomical support around the heel and tarsal area, improving stability, comfort, and pedaling efficiency.

Strategically positioned ventilation holes align with the openings in the outsole, promoting airflow and helping maintain a comfortable internal environment.

The supportive construction contributes to efficient power transfer while reducing discomfort during longer cycling efforts.

EPS Carbon Power Sole 8.0 – Efficient Power Transfer

The Gaerne EPS Carbon Power Sole 8.0 is engineered to provide an excellent combination of stiffness, comfort, and pedaling efficiency.

Constructed from carbon-reinforced nylon, the outsole delivers reliable rigidity while maintaining a lightweight and durable design.

With a stiffness index of 8, the sole provides efficient power transfer while offering a balanced level of comfort.

Its thin profile helps minimize energy loss during pedaling, while the anatomically shaped plantar arch improves foot support and stability.

Strategically positioned ventilation openings and internal air channels enhance breathability, helping keep your feet comfortable during intense racing conditions.

The sole also features non-slip front inserts and replaceable rear PU heel pads, providing additional grip and practicality when walking.

With 9 mm of expanded cleat positioning adjustment and an integrated alignment scale, cyclists can easily fine-tune their cleat position and reproduce their preferred setup.

The sole is designed for compatibility with common 3-bolt road clipless pedal systems.
