We’ve taken our lightest, World-Tour winning shoe and made it even better. We remastered our superior racing shoe with premium performance, stiff power transfer, exceptional comfort and made it the most breathable shoe yet. If your feet get sweaty as you ride, but you don’t want to compromise power – the F-XX XD-Knit is for you. Our pro-tour riders all say the same thing “it is the most breathable shoe they’ve raced with”.
The F-XX Knit sports a similar profile to the F-XX II and features the elite R500 carbon fiber outsole for maximum power transfer. The footbed is sculpted with a supportive cushion that helps to increase blood flow, reduce hot spots on your foot and ensure that your power is going directly into the pedal for maximum performance.
The new upper uses a triple layer of extra-strong nylon yarn of our development XD-Knit that is super breathable and will keep any rider's foot cool on those hot, long rides. The new XD-Knit is durable, will keep riders' feet in place, and won’t stretch. This seamless upper has a sleek look that is complete with a single new dial to optimize closure on a critical foot zone.
Sidi Size Guide
*Customers switching to Sidi Shoes or from Sidi;s more than 5 years old, may not wear the same size. All Sidi's, except for winter shoes, are built on the same last, but differences in patterns and materials so keep this in mind when switching between Sidi models. Every Sidi Shoe (except triathlon models) from 2002 onwards is stamped with its size and last type (and M indicates Mega or W indicates women's), Usually on the tongue.
Standard Width is considered as a D width
Mega = EE shoe fit 4mm of extra space across the ball of the foot. If you have high-volume orthotics you may feel more comfortable in a mega shoe.
Women fits - "Women specific" shoes are a narrower and smaller version of the regular fit option. The heel and ankle areas have also been narrowed.
How do I know if its a good fit?
Some people have narrow heels, if you know this to be true we recommend getting a shoe with a heel retention device. This will allow the heel to be narrowed.
Is it too small? If you stand up with your shoes on and your toes are touching the front, your shoe is small. You don't want any toes touching the front of the shoe, this will create hot or numb toes on long rides. You want to be able to wiggle your toes a bit, but not feel like they are "sloshing around"
Tip* Try on your new Sidi Shoes with the cycling socks you normally wear
If the shoe doesn't fit? Don't worry, we offer a 1 free resize policy to make sure you are very comfortable on your bike
