One thing that I do to keep my feet healthy is to elevate them whenever I get a chance. This helps to reduce swelling and improve blood flow. I also make sure to drink plenty of water to stay hydrated, which can also benefit my feet and overall health.
I agree with wearing comfortable shoes, but I also make sure to keep my feet clean and dry to prevent any infections. I also trim my toenails regularly and apply moisturizer to my feet to prevent dryness.
