FWIW, I was getting hot-spots after a few hours with my Asics Gel Challenger 9s. I swapped out the stock insoles for some Superfeet orange and I no longer get hot-spots. Out of the box, the shoe was comfortable in every other way.
I've found the same to be true for my numerous other tennis shoes, running shoes, hiking shoes & boots and cycling shoes. I don't always swap the insoles, but when I do, I prefer Superfeet orange (except for my cycling shoes, which get Specialized footbeds).
As always, YMMV.
