Lifting the feet (5)
I believe the answer is:
theft
'lifting' is the definition.
(I've seen this in another clue)
'the feet' is the wordplay.
'feet' becomes 'ft' (I've seen this in other clues).
'the'+'ft'='THEFT'
(Other definitions for theft that I've seen before include "Lifting" , "Dishonest taking of others' property" , "crime incident" , "Illegal act of taking" , "Pilfering" .)
