Choosing the right shoes is crucial in preventing discomfort and long-term back pain from standing for extended periods. Shoes with wide and flat outsoles help distribute pressure from standing, while cushioning in the ball and heel of the foot provide extra support. Built-in arch support or the option to insert your own can alleviate discomfort, especially for those with flat feet. Additionally, take frequent breaks to stretch and move around, and consider using fatigue-reducing mats in your work area.
