Not handy measures? (4)
I believe the answer is:
feet
'measures?' is the definition.
(foot is a kind of measure)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for feet that I've seen before include "Old measures - that fill shoes" , "Paws" , "Have both on the ground to be practical" , "supporters?" , "Linear Units of a third of a yard" .)
