Hello from Germany,
recently I have often had pain in the front of my right foot after glide-walking. When I walk, I bend my upper body slightly forwards so that the gluteal muscles can work better and I also land on slightly bent legs, as was shown in the foundation course. I also try not to let the feet kick out too much forward. In the long run, however, there is probably too much weight on the front part of the foot, so that it really hurts at some point. I guess I'm doing something wrong. I never had any problems with my feet before. Basically, I think glide-walking and the idea of stretching the psoas with every step are great. It already helped me a lot with the pain in my lower back and I also got a lot more flexible.
Maybe it also could have to do with that my right leg is a little shorter than the left?
