“The greater the compressive strength of the sole, the less deformation it undergoes under high pedaling forces. This directly improves power transfer efficiency—every bit of force you generate is delivered more directly and completely to the pedals, minimizing energy loss within the sole structure.

This becomes especially evident during high-intensity efforts such as sprinting, where the feedback underfoot feels more solid and immediate. For riders, this means a significant improvement in pedaling efficiency—the power pathway from foot to pedal becomes more direct and efficient than ever before.

The Santic Ultimate Surge cycling shoes are built upon this very principle.”

One-Piece Full Carbon Sole — Up to 223KG Compression Strength

The standout feature of the Ultimate Surge is its full carbon fiber laminated outsole, constructed without the traditional foam sandwich layer.

This design significantly enhances overall stiffness, delivering a compression strength of up to 223KG, far exceeding most cycling shoes on the market (typically 130–160KG).

Under high-power efforts such as sprint finishes, this high stiffness effectively reduces power loss, ensuring that every watt of energy is transferred directly to the pedals.

The outsole shape follows ergonomic principles, balancing rigid support with a natural fit to help riders push their performance limits more efficiently.

3D Ventilation System — Where Aesthetics Meet Function

The upper combines laser-perforated ventilation holes of varying sizes with flowing fabric patterns, creating a distinctive visual identity through the interplay of points and lines.

Beyond aesthetics, this design forms a three-dimensional airflow system that significantly improves heat dissipation during long rides, keeping feet cool, dry, and comfortable.

Easy-Clean Upper — Ride More, Maintain Less

To address post-ride maintenance concerns, the Ultimate Surge features a TPU-coated, vacuum-laminated seamless mesh upper.

Its smooth and durable surface resists dirt adhesion, allowing dust and mud to be easily wiped away. This lets riders focus more on cycling itself, without worrying about gear maintenance.

Upgraded Closure System — Stability Meets Convenience

The heel adopts a TPR-injected stabilizing cup with an integrated reinforcement plate, ensuring the heel stays securely locked during power transfer for enhanced stability.

Equipped with the ETIE L10-C alloy dial system, the shoes support quick entry and exit, as well as on-the-fly micro-adjustments while riding. This ensures a secure, full-foot fit, delivering consistent comfort and reliable support during long races or training sessions.
