I set some alarms on my "task scheduler" to go off every hour and tell me to get up and do squats or climb stairs. Sometimes I listen. Otherwise, I work on a gorgeous college campus and can just go walk to a store or something.

I take a walk or lift weights at lunch. Sometimes I jog. Sometimes I bicycle commute. I hike on weekends.
As for not sitting, there are lots of scenarios.
1. Jobs where you don't sit. I've worked in food service and sold flowers on a street corner. I did these two jobs for a total of 12 years so that's 12 years of my life where I never sat down at work.
2. Nude modeling. I did this for a while. There is no pose you can hold for 3 hours that doesn't hurt. If I was going to answer your question of "what's the longest you didn't sit down" my answer would be the 3-hour sculpture class where I did a standing pose for three sessions, even though I've had to stand for longer than that.
3. Long distance hiking. I spent 3 months two years in a row just walking all day. Start walking at 6AM, stop walking around 6PM to 8PM. Only sat down to eat (sometimes I didn't even sit to eat) or on "weekends".
As for barefoot shoes. After I did all that long distance hiking I couldn't stand regular shoes and my feet were all broken from "motion control" shoes. So I started learning about how shoes cripple your feet. I eventually made all my own shoes. The best ones are like the sandals sold by Native Earth. Way better than Luna sandals with the annoying thong between the toes and fussy tying. I wear my Native Earth sandals all summer. In winter I wear either shoes I've made myself or lately I've found some decent New Balance 730 and some Sanuks that I like. I've also got some Keen hiking shoes that I wear 2 sizes "too big" with really thin socks so they are all floppy. I like them that way. The heel on those suckers feels really high, though.
