Been working on increasing dorsiflexion with these so that my ankles stay grounded. My feet come out at an angle slightly, however, I noticed that the athlete's ankles come out slightly in the video, too.
This -im is always fun. I have been able to do these barefoot, for a while now. I still feel a little pressure on the inside of my knee, near the vastus medialis (which is due to a bone spur), but as you can see that pressure hasn't/doesn't limit my mobility here in any way. Let me know how these look objectively because at this point I'm not sure how I might improve upon them if I were to need to.
