Sidi Aeron gravel shoes review – much improved fit but not as light as you'd expect
The fit and new dials are superb, but not without flaws
The Sidi Aeron shoes represent Sidi's latest high-end off-road race option, featuring an updated Millennium fit system that widens the toe box and straightens the last for improved fit. The shoes retain Sidi's modular design but with a refined Nuun 001C dials and sleek silhouette. The heel adjustment system remains unchanged, paired with no-stretch Firmor X materials to offer enhanced stiffness and breathability, making these shoes suitable for fast-paced, high-intensity off-road scenarios. Over 1,000km of off-road testing confirmed their performance.
The shoes come in various sizes (36-48) and colours (White, Black, and Orange), with an orange and black special edition available. The new design focuses on reducing parts, slimming down the rear ankle retention system, and simplifying the dial mechanism. The carbon-fibre sole is protected from scratches, and the Firmor X material provides support despite its lack of stretch.
During testing, the Aeron shoes demonstrated significant improvements in fit and stiffness compared to previous models. The toe box provided ample room, and the overall stiffness allowed for efficient power transfer, especially when using WolfTooth DEL pedals. The dials proved to be easy to use and adjust, even off-road, while the Firmor X upper strands maintained structural integrity.
However, the included insole was described as basic, lacking arch support. Despite this minor drawback, the Sidi Aeron shoes represent a substantial upgrade in performance for gravel race applications.
