Yes, you would have to use some of your carbon credits to pay for the delivery and manufacture of the shoe. The product would have both a monetary and a carbon price. If you don't have enough credits, then you can buy some on the spot market from someone who isn't using theirs up.

This would incentivise repair of the shoe, as it may require fewer carbon credits.
