In cricket, they go to leg (4)

I believe the answer is:
pads
'in cricket they' is the definition.
The definition suggests a plural noun which matches the answer.
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for pads that I've seen before include "Treads" , "flats?" , "Blocks" , "Protective guards worn by sportspeople" , "Lines, or stuffs with soft materials" .)
