We remastered your favourite entry-level MTB shoe to be even better. This classic, yet affordable high-performance shoe is sleeker, more breathable and lighter than ever before.

Constructed with a high-quality triple layer of extra strong nylon yarn of XD-Knit to keep your feet secured without ever getting too hot. This super breathable shoe has a seamless upper constructed with TPU protection and features reinforced toe support. The shoe features three Velcro straps to ensure a precise and secure fit that is easily adjustable while riding. We upgraded the mesh heel lining and replaced it with leather to keep your heel safely secured in your shoes and gives the remastered entry level shoe a more sophisticated look.

The F-55 Knit features the M250 MTB outsole, constructed from nylon for superior power transfer. This shoe has dual density sole lugs that increase your terrain grip, as well as removable toe spikes for cyclocross traction. The full length arch support ensures your sole won’t pack out over time.

Cycling shoe sizing guide

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
