Step 1: stretch Step 2: put your hand on your foot, so your thumb should be on the sole of your foot and the rest of your fingers should be placed on the top of you foot. Your knee should be matching the knee on your other leg Step 3: bend you back and with your other hand try to put your it flatly on the ground. (your in bent leg MUST BE STRAIGHT). Step 4: try and pull your bent leg higher and higher. It may take up to 3 wks to do a fully back leg mount (that's if you practice for at least 30mins every day)! Good luck :)
One remedy would be amputation above the knee joint. I suggest you visit your doctor before taking such a drastic step.
If your foot pops with every step you take and you have a sprained ankle, you need to see a doctor. You may have a broken bone that needs to be reset before it heals up. An orthopaedic doctor should be able to help you.
That's the characteristic Prussian (and later German) military 'step' used in formal march-pasts and on parade. The main feature is that the soldiers don NOT bend their knees when goose-stepping. It was adopted by most East European armies, too. Look, if you can, at old newsreels and the like, even old photos. There's something unmistakable about marching from the hip, without bending the knee. :)
