I don’t know how large the market is for people with preferences such as I have,
I believe a part of this is the baby boomer wave. I suspect most people of that age are much more concerned about comfort than looks. I know my wife won’t let me buy Sketchers because of the lact of “cool” styling, but if I was single, I suspect I would have a few pair. So as we continue to age, I think we will want more sketchers.
Granted, they are selling more overseas where my theory probably does not hold water.
