Hey ankling is good but I find if I think about it too much I get too jerky and inefficient which leads to joint problems. So I do what I did when I ran cross-country/track of imagining my joints moving in circles which does wonders for my form and efficiency. I end up going super fast and when I try to concentrate on bumping up my speed I just end up feeling frustrated at how slow I am going and make jerky movements rather than efficient ones which just makes things worse.
