I picked up some after market all-weather mats, too. Excellent investment! I was torn between WeatherTech and Husky Liner, both are excellent quality.
I went with Husky Liners, because I felt they offered the best coverage. They completely cover the footrest (dead pedal), and the gas cap pull lever. I did have to cut the nubs on the Husky's around the gas cap lever, otherwise they will shred your finger when you reach under to pull the lever. But it was a super simple two minute process with a razor blade.
Either way, either brand, they are a must have for Crosstrek's.
