If it is a well sprung floor such as a suspended wood floor then that is a bit different as it‘s the sort of floor that is constructed for ballet and gymnastics, but this is why ballet companies invest thousands in a portable floor to bring to theaters on tour, as they cannot risk repeated jumping on hard floors.

If you are going to do this for a very short time on a good floor then you may well be fine, but the damage builds over repetition.

Amen. Last year I did the Shred barefoot, and I ended up really hurting my feet. I had to see a physical therapist a few times each week, and short walks were very painful. I always felt fine while doing the Shred, and then BAM, foot problems. My podiatrist said working out barefoot was definitely to blame. Yoga is the only thing I do barefoot. Jumping and lifting require shoes for me.
