Barefoot is where its at, however you’ ll need some barefoot shoes to do it properly
Okay, half right with the barefoot thing. Big, important part, especially if you’re getting knee pain –
GET A GAIT ANALYSIS AND SOME PROPER SHOES.
Sorry, did I say that loud enough?
Honestly, it could make a massive difference. Yes, it means spending some money, maybe, but if you’re running in the wrong shoe, it’ll injure you more than it’ll help your fitness. Barefoot/Minimalist shoes don’t work for everyone, same as any other type. Get a proper analysis from a decent shop (I use Accelerate in Sheffield and heartily recommend them) and listen to their recommendations. Most will do analysis free if you’re buying shoes then and there.
Knee pain could be just about anything from ligament or cartilage issues to mask-tracking and misalignment of the patella. If the pain is down the outsider of your knee, it could be ITB problems, which often stem from gait issues or pushing too hard too fast. In which case, back off, simmer down and give it a chance to recover.
