I got mine from the dealer the day I picked up my Soul - a very worthwhile investment, sure saved a lot of mess and great with the lip around it. I would imagine the 2014 version would be shaped a little different. They are made for Kia by Weathertech.
I can't find any info to says Weathertech makes the Kia mats. They certainly aren't "the same" even if they are made by the same company. There are concerns about coverage for the "dead pedal" and around the floor mounted accelerator pedal...in some markets? I'm on the fence about getting OEM or Weathertech...here in SoCa.
at my last visit to my local dealer I spotted this display and asked if they were available for the Soul and they are. They are quite a bit more expensive than the WT, which they can still obtain, but these look really tough with sort of a fibre back. Just throwing it out there as another alternative
