Boost, schmoost. I bet what they teach in "Robes Enchanting 101" applies just fine to enchanting of pants.
It would be nice if shoes were split from leggings. Frankly, I still miss the Morrowind armor setup where you could wear a shirt, pants, shoes/boots, greaves, cuirass, left and right pauldrons, left and right gloves and a helm, if you so desired. You could create most psychedelic combinations of mismatched, asymmetrical armor...
