I don't think that running making you all that shorter.
As we age our bones marrow density might get little bit shorter as it regenerates usually but running putting pressure on bones keeps them strong and I guess it's not the biggest factor.

I guess your body mass specifically muscles are getting more leaner that could be the literal cause of losing your cm.

Well there is a period when we keep growing after we hit puberty but it's not forever, our growth plates between the bones joints closes by 25 sometimes even 30 to fully close the plates and it depends on the person.

Increased consumptions of dairy products can really boost your growth as it's the main growth factor.
You can't really growth hormones now if you already turned 20+ because it's not gonna work but you could constant your doctor. There are also things like mk677(kind of growth hormone) very powerful for full body growth (move with caution consult your doctor before using).

Bottom line is your height doesn't matter so much to others as much as you feel, because you are short doesn't make you all that imperfect, you should feel good about yourself.

I don't think hairy feet protects you all that much from cold because you need lots and lots of hairs for that like the very early men but because it's still left in our DNA from the early men we still get a little of it.
If you feel embarrassed because of your feet hairs you should consider doing permanent hair removal surgery, it won't cost you much and in simple terms it's just a laser burning the hair follicle entirely so it never grows back up on it's own.

Well it was a very long reply sorry for that I really like to keep them short and straight to the point but had a lot to talk about. I guess I helped you in some way. Keep steeming Warm Regards.
