Tell me, How does the ocean greet the shoreline?

If athletes get athlete’s foot, what do elves get?

As I am, a green symbol of vitality and endurance But swap my second and third, then spell me in reverse and my meaning changes to make something weaker

If yellow, a mean fellow If leather, lasts forever If it's hot, you'd better not If on book, it's a good look

Remove my third and I be chasin'. Remove my second and inside I'm sizzlin'. Remove nothing, and leaders be freakin'.
