tread

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

'a step' is the definition.
(I know that step can be written as tread)

'new trade' is the wordplay.
'new' indicates an anagram.
'trade' with letters rearranged gives 'TREAD'.

'taken to obtain' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.

Can you help me to learn more?

(Other definitions for tread that I've seen before include "Trample" , "Walk or step like pattern on tyre" , "Moulded part of a tyre" , "Put one's foot down!" , "Grooved surface of a tyre" .)

I've seen this clue in The Globe and Mail.
