Relieves ball pressure
These are really great arch supports.  They provide arch support and heel cushioning, and they relieve pressure on the balls of your feet.  I dance salsa sometimes as much as 15 - 20 hours a week, and using these supports really helped ease the soreness in the balls of my feet.  They fit in all of my shoes and I've even walked 7 miles at Disneyland in a day wearing them.
