The Lange SX 120 is a great ski boot for advanced to expert skiers that have a medium to narrow forefoot, and a medium to narrow shaft of the leg. Lange's Control Fit Liner has a seamless toe box that improves the comfort of your toes, anatomical padding along the ankle and heel pockets to prevent your heel from slipping in the boot, and an instep pocket that improves your circulation for better blood flow and warmer feet. The Natural Flex of the SX 120 is more upright with a 4 degree ramp angle that gives you a more efficient power transfer on modern wide and rockered skis, which reduces the amount of energy it takes to you to make your skis do what you want them to. The Ultra Grip Soles improve your shock absorbing ability over rough terrain, and smooth out the ride for you, when you really start moving. The SX 120 utilizes Lange's Easy Entry Concept that has a softer plastic over the instep area of your foot that make is easier for you to enter and exit the boot. If you are an aggressive skier that is looking for a powerful flex in a ski boot that fits wider than most performance ski boots the Lange SX 120 will make a great choice.

I purchased pair of SX 80's a few years back, so I was very comfortable with the fit and form of the SX line. It was very important to me that the a boot for me have a wide last. Most wide lasts still are very narrow. The SX line offers a right-size IMHO because I really dont wear a wide shoe otherwise.
The boot is comfortable for all day skiing and performs well. I chose it because the liner seems slightly more comfortable than the Lange RX and XT liners which also are built around a narrower last.
My only complaint if any is that the boot does not come in a stiffer model. A 130 would be very nice.
Skis.com was great. They are my favorite online ski source at this point.
