I have had the all weather floor mats in my car for months now. They don't get wet much, but when I get in after washing my car I don't notice any slipping. The mats are essentially rubber, so they don't seem slippery to me.
I don't have the trunk mat, but just ordered it a few minutes ago and should have it later this week! I can post a picture of it installed when I get it. It may be a little different than yours since my car is the i5 version, but probably 99% identical apart from how it fits to the floor space.
I hope this helps.
