How do I get these floor mats to stop curling up?

Hi all!

I have a NA Miata, and purchased these second-hand aftermarket floor mats for it on the cheap.

I enjoy the style, and the price was good, but for some reason they keep curling up specifically in this area, making clutch use difficult.

Anyone have any ideas on how I can get it to stay down?

I’ve tried folding it the other way, putting LOTS of weight on it, etc.

Thanks!
