Sidi Aeron Men's XC/Gravel Cycling Shoes
The Sidi AERON Cycling Shoes' ripstop upper, featuring protective rubber bumpers, offers outstanding durability and abrasion resistance without adding weight, shielding you from trail debris while maintaining agility. A pair of NUUN 001C aluminium dials provides micro-adjustable fit control for a secure, comfortable profile, while the adaptive instep and UNUM Ergo anatomical tongue work together to eliminate pressure points and deliver a truly customised fit. Meanwhile, the Firmor X internal reinforcement and tool-free heel adjuster keep your foot perfectly aligned and stable, even during explosive efforts on tough climbs.
Underfoot, the X2FC full carbon sole with rubber lugs boasts a stiffness index of 11/12, channelling every watt of power directly to the pedals while ensuring excellent grip when you’re off the bike. Add in independent cleat adjustment for optimal positioning and replaceable heel pads and dials for long-term performance. Whether you’re chasing mountain bike XCO podiums or exploring remote gravel tracks, these shoes deliver the efficiency, comfort, and control that elevate every ride.

Sizing note: Sidi shoes run small and have a narrow fit. On length: if you're between sizes, size up. On width: if you have a wider foot, choose the Wide Fit version — don't try to compensate with a larger size in the standard.
Measure your foot by following these steps:
1) Place a piece of paper on the floor with the shortest side against the wall.
2) Put your bare foot on the paper with the heel pressing against the wall.
3) Make a mark on the paper at the tip of your longest toe.
4) Use a ruler to measure the distance between the mark you've just made and the bottom of the paper where your heel was placed. Round to the nearest mm.
Always measure both feet to get the most accurate size. If you find that your right and left foot are different in lengths, it is recommended that you opt for the larger size.
