I personally think so. Trainers with no socks are just PERFECT for me.
Racers aren't as comfortable to me because I need stability shoes and the trainer has enough stability. My foot tends to turn in a bit more than in the trainers.
I have more issues with the Lunars. It's comfy, but its not the same. Very little stability so there are pronation issues, but I don't run in them. Without the sockliner, the trainers feel more locked down, unlike the Lunars which don't have the same tight fit. Plus the sockliner rubs a bit, ironically.
I got my parents two pairs each of the Lunars and that is all they wear now. But the Lunars seem more mainstream than the trainers/racers. I doubt they'd wear the trainers/racers because it's more of a technical shoe.
Lastly, I think the colors pop more on the trainers/racers. For instance those new red racers are smokin. Not the same feeling towards the Lunars.
It's a preference, of course.
