The RS 110 SC from Lange was designed for junior racers and women. It is the step up from the RS 90 SC with a stiffer flex of 110 and a thicker power strap so ideal for those junior racers that have progressed past their previous boots, or for women wanting a mid flex racing boot. The Dual Core technology has been developed for racing to help with energy and flex control throughout the turn. The boots have also been developed to offer comfort as well as power transmission combining two things - anatomic shell and Lange's thermo-formable Dual 3D liner.
