What are my rights to return these?

Fly Wedge Boots, brought 3 months ago.....but can't find my online receipt :(
2 holes appeared in the sole and I had to take to the cobblers. When I picked them up he had had to put a slightly different colour repair and went ahead anyway :0
Do I have any rights to return these to Fly?

No

Think you should have contacted them before getting them repaired. You only need proof of purchase, not receipt.So it showing on a statement would show that. But now you've had them repaired I'm not sure where you would stand.

Nope, you have had them repaired by a third party.

I would complain to the cobblers for repairing them in a different colour tho
