I received a new pair of Carminas that came with a slight tear on the back seam. The seller is willing to replace them with a new pair, but has asked if I would be willing to keep them for roughly 25% of what I paid and have a cobbler repair them. Is this problem an easy repair? I'm inclined to accept the offer if the repair can resolve the issue without leaving an obvious sign of the original problem (large stitching or an extra piece of leather sewn on). I'm inclined to return them if there will be structural integrity problems or an unsightly repair. Does anyone have any thoughts?
