I'm another of the many on this forum who hike in trail runners. No blisters, far more comfort, actually more support for my ankles than the boots had. I will NEVER go back to boots! Do remember that an additional pound on your feet is equivalent to another 5 lbs. on your back (even the US Army says this).

If you are climbing rather than hiking, that may be a different story, but even climbers are using lightweight footwear these days.

In any case, everyone's feet are different, so anything any of us might recommend would most likely be uncomfortable for you. Go to several different stores and keep trying on footwear. Or you can order from one of the number of online shoe places that features free return shipping if the shoes don't fit.
