Crippled in heel on type of golf course (4-4)

I believe the answer is:

nine-hole

I'm a little stuck... Click here to teach me more about this clue!

'golf course' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'crippled in heel on type' is the wordplay.
'crippled' is an anagram indicator.
'type' indicates anagramming the letters.
'in' anagrammed gives 'ni'.
'heel'+'on'='heelon'
'heelon' is an anagram of 'nehole'.
'ni'+'nehole'='NINE-HOLE'

'of' is the link.

Can you help me to learn more?
