With the new closure system, the shoe can be put on and taken off easily and quickly thanks to the Tecno 3 Push closures located close together. By placing the closures on the instep, the system allows for optimal, symmetrically balancing pressure distribution. In addition, the shoe has aerodynamic advantages and overshoes are also easier to use. With "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 replaceable.
