Recently I was introduced to jogging. As a side effect I adopted a toe-contacts-first walking style. The heel usually contacts the ground towards the end of the step, taking up a lot of weight, but briefly. I am happy with the lack of load to my knee joint and also the firmed up calf muscles.
However, I am being warned that that toe walking wears out other joints than the knee. And can see it is a known malady.
Is it unhealthy to walk toe first?
