willni,i have the same mats in mine-well,sort of.
They look great,but are susceptible to heel imprints after very little use,making them look like you’ve had them for years.
So much so,I purchased some genuine rubber mats and swapped the drivers mat for the rubber one,as it was doing my head in,the rubber mat being more robust for daily driving.
Mats are often reinforced or double layered on the heel area-you see this on cheaper ones,you’d think for the price these gti mats are,vw could have done better.
Or it could just be my size 11 feet that’s the issue!
