What 8 hours on your feet really does to your body

“Move more, sit less” is familiar health advice, reflected in federal recommendations to reduce sedentary time. But where does that leave the worker who barely gets a chance to sit? For nurses, retail staff, restaurant employees, teachers and other professionals, the workplace-health question extends beyond getting out of a chair. The demands of a long shift go beyond the shoes workers choose. What actually happens to the body during eight hours of standing and walking, and how much difference can the way that work is organized make? The scale is substantial, KURU Footwear reports. The National Institute for Occupational Safety and Health, or NIOSH, estimates drawn from a 2015 national survey identified roughly 97 million working adults whose jobs involved frequent standing or walking. More recently, federal data show that waiters and waitresses spent an average of 98. 6% of their workday standing in 2025, a category that includes walking.
