has anyone crocked themself doing this? Having always been a heavy heel striker (and 6'5" 90Kg) I started with deliberate forefoot running maybe 3 months ago (with a vague thought of going on to barefoot) mainly during intervals and shortish tempo runs. The change felt great in many ways and clearly improved my running style to external observers, quickly became natural and had a marked effect in speeding up my descending as I learned to land forefoot first and reduce contact time. Unfortunately I have developed an injury to the medial ligaments of my ankle making any dorsiflexion painful even on normal daily activity and I'm barely able to train. It's difficult to unlearn the new more natural feeling gait and I'm hoping my physio's sorting me out so i can continue to progress....but it's a right pain in the arse at the moment. Any other similar experiences? How did you get on?
