As long as you aren't packing that bag to the seams, consider just sliding your feet under the bag.

I tend to be a "1.5 bagger" in that I have a small duffel/backpack in the overhead and my backpack/messenger bag for inflight stuff. And the latter gives me easy access to my steam deck or my kobo but is also more than small enough I can just slide my legs under and get a significant amount of legroom. ALSO has the benefit of making me lean back in my seat which means I don't care if the person in front of me "reclines"

A buddy of mine is 6'5" and he is just in hell no matter what. Like, anything short of one of the enhanced legroom rows is gonna suck whether he has a bag under the seat or not.

I put it under the seat during takeoff/landing, then move it under my legs the rest of the flight. Frees up space for your feet while providing additional support under your legs.

You have the long stride advantage so it evens out
