On the Moon, maybe.

And in orbit. Note how they attach themselves to the work platforms and the

I've got to agree with Greg here. One of the things you need to do
during EVA's is to anchor yourself so you can apply forces to other
objects without having yourself moving around. Remember for every
action, there is an equal and opposite reaction.

Using your feet to anchor yourself to a work platform, say on the end of
the shuttle/ISS arm, allows you to put force on other objects with your
hands. Also, this gives you some mobility of your body without having
to move your anchor point (i.e. bend your leg joints and you can move
left/right/up/down by quite a bit). You can also use your leg muscles
to help break something free.

If I had a dime for every time I had to use a breaker bar and my leg
muscles to free a stuck nut or bolt on my car...
