Replying to Boots too flexy?

I just got the Lange xt free tour 130 LV in 27.5. Skied them about an hour after they got heat molded to my feet and they are pretty flexy. Anyone else notice this? Definitely not something super negative that makes them unskiable, they actually were making me focus on my balance more which was fun. Maybe it’s because they never got to cool down a little idk. My last boot was the il moro which was 120 flex, it seemed stiffer tbh. Maybe the Lange has a much more fluid and forgiving flex then the dalbello. Looking to hear what folks have experienced.
