How much work will it take to a lift a 2-kg pair of hiking boots 2 meters off the ground and onto a shelf in your closet?

The boots have to acquire additional gravitational potential energy of 4 kg-m. That's the
minimum work you have to do, depending on the efficiency of your muscular efforts.
====================================================
Another contributor spotted my blunder on this one, and hostilely but correctly called me on it.
Unfortunately, his correction was so belligerently stated that the supervisor removed it, so
I'll now supply the correction:
Work is (force) times (distance).
The gravitational potential energy added by lifting the 2-kg object ... and the work to get it there ...
is the weight of 2 kg times the distance.
The weight of 2 kg is (m g) = 19.6 newtons.
The work is (weight) times (distance) = (19.6) x (2) = 39.2 newton-meters = 39.2 joules
(Plus of course the additional energy that your muscles have to dissipate in order to generate
39.2 joules of useful output.)

Work = (force) x (distance) = (weight) x (distance) = (mass x gravity) x (distance)= (2 x 9.8) x (2) = 39.2 joules
