Comfort Flex Tongue is a flexible boot tongue designed to adapt to the movement of the foot while riding. The design increases the range of natural ankle flexion, making movement more free and comfortable. The soft, well-contoured construction reduces pressure on the instep and improves the fit in the front of the boot.

The advanced design of the insole improves the fit of the foot inside the shoe and supports its natural position while skating. The contoured structure stabilises the arch of the foot, increases comfort and helps to evenly distribute the pressure generated during dynamic pushes. This allows for more efficient energy transfer to the skates and reduces fatigue during prolonged activity.
