Knee Problem

Are you locking your back knee at pushoff?

I remember from when you visited Palo Alto that the arches in your feet are not pronounced. If you focus on maintaining your arches, this will prevent your knees from hyperextending. Arch supports can help with this, both by preventing the foot from distorting past a certain point (acting like a safety net) and also as a training device to remind the foot muscles to do their work. The way arch supports help keep your knees from hyperextending is that it takes a huge amount of flexibility in your calf muscles to both arch your feet and hyperextend your knees. Since you probably don't have that flexibility, if you arch your feet your knees won't be able to hyperextend your knees. It's a backhanded way of addressing the problem, but you get the bonus of strengthening your foot muscles in the process.

Hooray!
