Those official Nissan rubber mats are ****.
First problem:
If it's a manual and you wear size 10 shoes, the distance between the clutch pedal and one of the ridges on the mat is exactly the same as the distance from the ball of your foot and your heel, so your foot gets stuck when you clutch. I almost rolled back onto a car behind me at traffic lights when the truck was new.
Second problem:
The rubber is too soft so the mat splits along the corners of the ridges. After less than a year, I had holes in my mat, especially under my left heel where it rests when I'm driving. I'm still on the lookout for a decent set of rubber mats for the truck.
