I read "Born to Run" about 3 years ago, and was pretty convinced. I ended up getting some 5 Fingers, which I wear a couple of times a week, but I don't care to run more than 3 miles in them because my calves get insanely sore. I mainly do CrossFit and sprints in the 5 Fingers.
Instead, I've just been wearing my old supportive shoes (Adidas Supernova with overpronation support) for 3 years. I run about 20 - 25 miles a week. I've also run a marathon in that time.
I've noticed in the last few weeks that my knees, hips, and ankles feel kinda creaky and achey when I run. I'm wondering if running on busted up old Supernovas might actually be worse than running on new super padded up Supernovas.
What do you think? Should I try to transition to running 100% in 5 Fingers?
