4-QUATTRO XT & 4-QUATTRO SL | Alpine Touring

Some days you like to skin up a mountain and ski fresh lines. Other days you like to charge through the resort, taking lap after glorious lap. We get it, and that's why we made the 4-QUATTRO XT ski boot. As a hybrid boot, it's both lightweight and stiff, with a single boot weighing just over three pounds while still retaining a 130 flex rating.
The 4-QUATTRO SL is the lightest GripWalk hybrid ski boot in its class. A low stand height and flex index of 120 provide the ideal balance of performance and comfort for all skiing pursuits. The shell and cuff are made from Pebax R-new®, produced from renewable, plant-based sources.

Difference between SL and XT?
Just flex?

My understanding is yes. SL is 120 and xt 130
