Your feet are important.
They connect you to the world and are the root of your strength. The foundation that your body and your power are built on.
I guarantee that your feet are probably fucked from spending your whole life cramming them into retarded modern footwear.
Your feet have been going through cock and ball torture your whole life, that's what causing your knee and back pain anon.
At least, I now know after years of knee problems that it was my feet all along. So lets have a tread about fixing our feet.
Look at your feet, if you answer no to any of these, you have work to do:
>you have a clearly defines arch
>your big toe is pointed slightly inward, with a clear gap between your other toes (pic rel)
>stand up in a normal, comfortable position. Where are your feet pointing? Are they pointing forwards, or slightly outward? (duck feet)
>can you run a 5k barefoot/in minimalist shoes without your ankles hurting?
Post anything from:
>fixing fallen arches
>fixing your gait
>fixing your duck feet
>Improving ankle strength
>minimalist footwear suggestions
>proper running form
