[Sorry - posted in wrong forum - moving this to 'Gear'.]
I usually hike in the Southern California hills in my NB running shoes but we are backpacking in a couple of weeks in Big Bend NP (desert level, off trail, lots of arroyos and loose rock, some mountain trails) so I switched to a NB 889 trail runner/hiking shoes.
The new shoes have a rock guard, tougher sole, etc... which will be more protective but there have been some sharp twinges in my ankles just walking around the house barefoot (never had these before).
Do I wear the older running shoes - knowing I will feel every rock, or just assume the new shoes will break in and the twinges will go away? Trip starts in 8 days so ostensibly there is time to soften/break-in the trail runners.
Thanks for your help.
