Fwiw now, I have owned both Husky and WT in recent years. I will agree with a previous post that the Huskys are harder plastic; less pliable than WT. Not really a negative but this made them more noisy, kinda. Depending on what kind of heels and soles your shoes had, there was more sound as you moved your feet. I would also say that, to me, they had a cheaper feeling albeit slight. The harder material was easier to clean imho.
As noted the backsides have spikes and they definitely won't slide around. They're actually a little difficult to remove from the car because of it.
They wore fantastic tho. We had them in a 50 mile/day daily driver for over a 100k miles and they held up great. My wife wears heels and while there is heel wear, there's nothing close to a hole. In fact I still have them (totaled car) and am trying to resell them on Craigslist.
I am shopping for mats for my EXL now and won't hesitate to get the Huskys, price considering. Both are made in the US which matters to me. EDIT just realized that Husky only sells the full set, front and rear. I don't really need rears and at these prices will only buy fronts.
