Ok, there’s quite a lot of confusion here in both the question and the answers.

No. Section 75 is a statutory requirement which makes the CC company jointly liable with the retailer if the purchase is between £100 and £30k. It can affect ANY liability arising from the contract, not just faulty or non delivered. (And the OP has a legal right to return under Distance Selling Regs)
Chargeback isn’t part of s75. It is a voluntary, not statutory, claim. Used by both CC and debit, but usually where they can still claim the money off the retailer. If they can’t, then despite “which” saying they
should pay, you’re likely to have a fight on your hands.
Now since the complaint here is about ONE pair of boots, for s75 to be relevant they must have cost >£100 AND be at least part paid by a CC. If the whole order was >£100 then I’m not sure, you might be better rejecting both pairs. If the cost was <£100, or paid by debit card, then you’re down to chargeback and fighting it out with your bank/card company, but there’s no statutory obligation and s75 doesn’t come into it.
