feet

when I am walking on a hard surface Concrete in my sneakers for some reason my bottom of my feet are in pain it also happens if I am walking on sand from the research I've done it might be several different things. It could be a heel spur or plantar fasciitis. Anyway which supplements can help...

I'm looking to improve my feet overall first off my nails get chipped a lot and then also the bottom of my feet get really hard where it's time consuming to get it fixed This causes me to have to spend money going to get spa treatment so they can really get in there and get rid of the dead skin...
