Boa dial for Sidi Tecno 3

Boa dial for Sidi Tecno 3 road cycling shoes: precision, comfort, and performance at your feet

When it comes to high-end road cycling shoes, Sidi is a name that consistently stands out. Known for premium materials, durability, and attention to detail, the Italian brand equips some of the world’s most demanding cyclists. One of its key features? The Boa dial system, known as Tecno 3 on Sidi shoes — a closure mechanism designed for maximum precision, comfort, and performance during long rides.

What is the Sidi Tecno 3 Boa dial system ?

Unlike traditional laces or Velcro straps, the Boa dial uses a micro-adjustable knob that fine-tunes tension across the foot. On Sidi road cycling shoes, this system is called Tecno 3, developed in partnership with Boa Technology for a cycling-specific fit.

Key features of the Tecno 3 include:

• Dual dial closure: positioned on the upper and the tongue for symmetrical, custom fit.

• Reinforced techno-fil cable: extremely durable, providing even pressure without hot spots.

• Micro-metric adjustment: allows on-the-fly tightening or loosening without removing the shoe.

The advantages of the Boa system for road cyclists

The Boa closure has become a standard for road cyclists seeking precision and foot stability. Here’s why:

• Millimeter-perfect adjustment: essential for long rides where comfort matters most.

• Even pressure distribution: reduces discomfort and numbness.

• Quick and easy mid-ride adjustments: perfect for changing conditions and terrain.

• Streamlined design: the system is integrated into the shoe without adding weight or bulk.

Why choose Sidi shoes with Tecno 3 ?

Sidi cycling shoes with the Tecno 3 Boa dial offer a perfect blend of performance, comfort, and longevity. Designed to hug the foot without squeezing it, they’re also known for their stiff soles—ideal for efficient power transfer—and their abrasion-resistant microfiber uppers.

Other noteworthy features include:
