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

'rubber sole' is the definition.
'crepe' can be an answer for 'rubber' (a type of rubber material). I'm not sure about the 'sole' bit.

'creep around in a type' is the wordplay.
'creep' anagrams to 'CREPE'.
However, I'm unsure how this is indicated.

'of' acts as a link.

Can you help me to learn more?
