I don't trail run, although I may start, I mostly run outside on the road. I was wondering if anyone uses these for road running? If not why couldn't you use a trail runner for road running? For some reason I seem to always be drawn to trail running shoes. I think it's mainly because I'm not too fond of the flashy type shoes that are indicative of road shoes, I love my Asics, but they, as are all road shoes are too busy and flashy for my taste. Also, my weight is 195, are these suitable for heavier runners? I tried on a pair and they felt great but they also felt like they may be a little soft, but then again I didn't run in them.

If you run mostly on the road, go for a road running shoe. It's gonna be much lighter (100grs average) and way less stiffer. The poor flexibility of most of the trail shoes, except for the onesthat are more "race oriented" comes from extra layers of material for protection and the insert that you find very often in the sole to protect from rock pinching.

Todd, its my opinion that you can use any trail shoe for running on the road. However, there may be some features in trail shoes that aren't necessarily needed for road running, such as a stronger toe-box area for when you kick rocks and roots, and extra grips/treads on the sole of the shoe to help you make those steeper climbs. Because of these features, you may find some trail shoes to be a bit 'clunky' or heavy for a road run. While you may have that feeling of driving an SUV down a flat paved road, you can still run on the road with these. I am not sure about these shoes for heavier runners, but I do know that Vasque shoes are among the best in the business so I can't imagine you having a problem with these not being supportive. If they felt great, go for it!
