if you are talking about the front floor mats. they are supposed to come apart around the sides. when you pull off the hard plastic tab on the bottom part, then you can pull out the carpet and just have a rubber floor mats. To put them back in, you will need to tuck them in around the sides of the rubber mat then snap the tab back on.
these are all season floormats, just the way they are made.
although this doesnt apply to the rear seat floormats.
Personally i like these floor mats bc i can remove the carpet for the winter and hose off the rubber mat in the spring and then tuck the carpet back in
saves me from having to replace the stinky white stained (from salts we use on roads) mats winter after winter!
