Softer feet? Feet expert

Hey y’all I’m at a young tender age of 22 ... why are my feet so rough!!!?

I’ve worked plenty of jobs requiring me to always be on my feet ( security being one of them) could that have anything to do with it? I’ve also had a baby so I never get the chance to sit down. My feet were never rough and calloused. What can I do? I want super soft feet. Calling all feet experts.
