Functional, but the fit is only so-so.
I had the big heavy rubber OE mats, and they don't contain dirt like the tray style liner. I also felt that they interfered with the clutch, but that could be partly the fault of my large feet. These Husky liner fit reasonably well, but there are gaps on the left along the door. They also still interfere somewhat with the clutch and behind the accelerator. Bottom line, they'll keep the car clean, but sadly, they're not perfect.
Good, but not the quality of WeatherTech
Bought Aries floor liners for my 2015 Subaru Impreza in early January. Bought floor liners from WeatherTech last year for my wife's 2015 Subaru Forester. Both fit fine; but the WeatherTech are a bit better fitting. WeatherTech quality is better as is the heft; and where Aries are smooth; Weathertech have groves whereby water pools to the rear; keeping it off your shoes. My vote goes to WeatherTech.
