The new UK (probably rest of Europe too) i30 genuine mats don't come with reinforced heel areas on the drivers side of the car like they used to.
As a result I now have a hole right though the carpet cause by the heel of my right foot.
I've treated the carpets very well, including scotchguarding them when new and just before winter. I've always removed them to allow them to dry when wet. They are only 13 months old.
To be fair the passenger ones still look OK, but the driver's one will need replacing soon. I'll be swapping to rubber mats like on my old car.
Disappointing considering the price.
