The 140 has a 40mm booster strap which in built into the power-strap. This means the boot can help to eliminate shin pain and give increased feedback/performance. The liner of this boot is a mix of cork an oil which allows for a more customised fit once heated.
Spine tech buckles give a closer anatomical fit. Dual cuff alignment allows for better interface between the boot and the leg.
There is an option with the RS Speed to adjust the flex of the boot. One is able to change the boot from 120-140 approximately in increments of 10.
The boot has a FIS regulated sole in both the mens and womens models. This boot is a plug boot, therefore heels and toes cannot be replaced. There is a positive to this in that it increases the power transmission to the ski.
