I do not have a set of floormats to offer, but I can point you to some good replacement mats that are the closest thing to original that you will find.
I have an 88 that I spent many years and several buckets of money restoring. I have a very good set of original floor mats in my car, but I'd been wanting to buy some replacements so that I don't wear out my DS mat from my right heel. I have checked out all the companies that make aftermarket auto carpet and floormats to try to find a suitable pair of mats. I had resigned myself to the idea that I would have to buy a pair of mats with a cut pile carpet, as I did not find any company that offered any carpet that was even close to the loop carpet that was put in the Fieros.
So finally this summer I decided it was time to buy a pair of mats so I could drive my car some more than usual. I decided to purchase from Auto Custom Carpets (
http://www.accmats.com/ ). While I was placing my order I discovered that ACC now offers loop carpet! So I selected the charcoal grey loop carpet for my new floormats. They are a single color carpet, unlike the two-tone carpet used in the Fieros, but this is the closest thing you're going to find today. Now some pictures:

In the picture above, the OE mats are at the top, the ACC replacements are at the bottom.

In this picture the OE mats are laid over the top of the ACC mats
.

This picture shows a comparison of the fabric.

Here's a closeup of the fabrics. The OE mat is two-tone, the ACC is single color.
The PS mat is larger than the OE unit, but it fits the full floor area of the passenger side of the car wonderfully. As a point of reference, these mats cost me $116 delivered to my door.
