I can't find all season floor mats or cargo liner for Kia Soul EV 2020 anywhere. I guess the car is too new and it takes time for 3rd parties to make them. If someone knows where to get those please share a link.
We had a similar problem when the first gen came out. Lloyds Mats were about the first as they just cut the rubber out of large sheets so they just need to work out the pattern. I just checked but even though they list the Soul it says "No EV" against it so you may just have to wait a little bit.
