My question: I'm hoping to register for the Oxfam Trailwalker this year. Will my Sprints be OK for the Trailwalker terrain or should I get a pair of KSO Treks?
After I got a stone bruise in my Sprints, I ran in my hubby's Treks (a touch big so I got a few blisters but still generally OK) and the Trek sole is a LOT more forgiving when stepping on the pointy end of individual stones.
