DescriptionThe whole story▼

A white boot says you care about how your kit looks, and the Crosscore 104 delivers that clean look on a sensible base. Sidi built this new off-road model for riders of all levels: microfiber upper, high-density TPU protection, four replaceable buckles and, by the manufacturer's account, a fit that is comfortable straight out of the box.

For riders who want a fresh, matching look on the track and on weekend trail days without paying for race-specific technology they may never use, the white Crosscore is an honest choice.

Key Features

  • Microfiber upper, roughly half of the boot's composition
  • Tongue thermoformed for shape, flex-back hinge for movement
  • High-density TPU zones over tibia, calf, ankle and foot
  • Anti-slip, heat-resistant insert at shin plate and calf guard
  • Asymmetric Flexion System: four polymer buckles you can replace
  • Advanced compound rubber outsole for grip and durability
  • CE certification to EN 13634:2017; EU 37–50, unisex

Materials and Construction

Sidi's list breaks the boot down clearly: microfiber accounts for about 50 percent, the TPU protection panels around 25 percent, the rubber outsole approximately 15 percent, polymer buckles and hardware about 5 percent and the inner lining, padding and heat-resistant inserts the final 5 percent. The thermoformed tongue keeps the front of the boot in shape, while the hinge at the back allows it to flex rearwards with your ankle. Country of manufacture is Bangladesh.

Fit and Comfort

Sidi labels the Crosscore a regular fit and describes it as easy to put on and flexible by design, with no break-in needed. Inside, a slim profile is meant to bring your foot closer to the bike for better feel on the brake pedal and shifter. Sizes span EU 37 to 50 for men and women alike.

Protection Layout

Every area that typically takes a hit off-road gets a layer of high-density TPU: the tibia, the calf, the ankle and the foot. The shin plate and calf guard add an insert that grips the bike and resists heat, so your inner leg is protected from the hot engine and pipe area. Sidi certifies the boot to EN 13634:2017 under CE rules, without stating individual performance levels.

Replaceable Parts

Longevity is part of Sidi's pitch. The buckles are made of polymer and can be swapped, and the brand also refers to replaceable inserts that extend the life of the boot. Our sources do not list the individual spare part numbers, so ask us if you need a specific piece.

Riding Scope

Sidi frames the Crosscore as ready for everyday off-road use and weekend adventures, with a sole engineered for traction and control on mixed ground. It is an all-rounder for practice laps, trail riding and club events rather than a dedicated pro race boot.

What You Should Know

The Crosscore has no membrane in its specification, so it is not waterproof, and no ventilation system is named. Sidi gives neither a weight nor a name for the sole compound. The no-break-in promise is a manufacturer statement. As an off-road boot, it is not intended for extended walking or road touring.

Colour

White 104 is predominantly white: shaft, shin plate, all four buckles and the heel cup are white, set against a black collar band, a black panel on the outer side of the upper shaft and a black outsole. The black Sidi logos on the shin and heel finish the look. It is a sharp, clean design that pairs with almost any jersey, and in daylight the light surfaces make the boot easy to see. The honest downside: white shows every bit of mud, chain grease and boot-on-peg scuffing, so plan on regular cleaning with water and a soft brush if you want it to stay bright.
