boots/shoes for backpacking

Hey there! I'm pretty new to backpacking. A while ago I bought some really nice heavy-duty boots (unfortunately they're hot and heavy), but last year I got some lighter hiking shoes, the Merrel Chameleon Arcs. I was wondering if these would be good for long-distance backpacking because I know that many people just wear trail running shoes. I want to try and go lightweight, so I wouldn't want to bring my 10 pound boots with me. I have good ankles and am in good shape. Also, I put orthotics in them (if that is relevent to my question at all). My pack weight would hopefully be around 25 pounds.
Thanks for any help!

The tool needs to be matched to the job. Tell us more about your plans.

I can't speak from an experienced backpacker's point of view but I have extensive experience with the Vasque Breeze hiking boots. I wear them every day for work about 8 months out of the year. My work involves hiking and surveying in rough terrain. I used a 1 year old pair for training with pack for 3 months and eventually hiking in the Grand Canyon. I never had a blister or sore feet. They give moderate ankle support and are very lite. I am about to purchase my 3rd pair.
