I currently wear Brooks Beast and they've been a lifesaver for me. I used to get foot/leg and back pain when walking/jogging in other shoes, but the Beasts cured that almost magically. I wear the Beasts when I go hiking, but I'm walking mostly in sand/grass and there are hardly any rocky surfaces that I have to walk on.
In the late spring, I'll be doing a few sections of Georgia (3 or 4 nights each time) and I was wondering if the Beast would be sufficient or do I need to get some trail runners? My first choice would probably be the Cascadias if I had to go with a different shoe, but I'm worried the back pain would return if I ditch the Beasts. Anybody have any experience wearing both these shoes, or either? I know some people hike in flip flops and all that, but realistically, do you think it's worth it to get the trailrunners?
As always, I appreciate any imput and advice.
