There are many exercises that stress keeping my toes and heels together with straight legs. My knees prevent this, and I'm wondering if there is another rule I should be trying to follow when I am supposed to have my feet together. My physical therapist assures me I do not have knock-knees because my hips aren't internally rotated.
On another note; my ankles collapse in. This leads to me having a flat arch in my foot. I've decided to take up barefoot running which is supposed to help build an arch. This is because barefoot running has you landing on the ball of your foot, using the rest of the foot as a shock absorber and spring instead of landing on the heel that modern sport/running shoes cause.
I'm wondering if there are any exercises I can start doing to strengthen the muscles in my feet that may help rebuild my arches?
