Not a nurse but I worked a lot of manual labor jobs that had me on my feet moving all day (e.g., home renovation work) and I can say that your body eventually gets used to that kind of work and the soreness becomes a persistent dull ache that honestly isn’t bad. Kinda like if you just work out daily.
Nursing may be different, and my experience may not apply, but I would think that you will get used to it.
Honestly the only thing I never got used to was standing in one place at retail work. Standing all day in the same spot is not natural and the body rejects it.
