Sidi Tecno III PUSH single

The central mechanism, Single tecno-3 Push System, creates a perfect tension balance between the inside and outside of the shoe. The symmetrical mechanism guarantees excellent closure and adjustment to any instep. With the "Push" button on the twist lock, the adjustment wing can be flipped open, making it even easier to adjust while riding. Like most Sidi small parts, the Double Tecno 3 Push system is interchangeable.
