Provide means of support for heel that hurts (5)
I believe the answer is:
endow
'provide means of support for heel that hurts' is the definition.
'endow' can be an answer for 'provide' (I've seen this before). I am unsure of the rest of the definition.
'support for heel that hurts' is the wordplay.
'support for' means one lot of letters go next to another (in a down clue, some letters 'support' others).
'heel' becomes 'end' (I've seen this in another clue).
'that hurts' becomes 'ow!'.
'end'+'ow' is 'ENDOW'.
Can you help me to learn more?
(Other definitions for endow that I've seen before include "Give qualities or abilities to" , "Provide with a source of income" , "Fund" , "Provide with a permanent income, say a school" , "Provide funds" .)
