The RX 110 W from Lange is a boot that is designed for women who ski over the whole mountain. The shell of the boot is made in what Lange calls Dual Core which means that two different rigidity grades of plastic have been combined in the shell which allows quick and easy step-in without making the boot softer in its performance. With an inner lining equipped with Dual 3D liner Pro technology, you get two different densities on the material which means that the liner fits well both around the foot and against the shell of the boot. With Lange's specific ShinControl for women, you get a better support in the tongue that is made of varying thickness on the sides to better fit the shape of the shin. The boot is equipped with Thinsulate insulation to better retain heat in really cold conditions.
