Be careful. I did the same and it worked fine until I started to run more than 15k at a time, when I started to develop issues with my metatarsals that still haven't gone away more than 6 months later. I saw a physio who specialises in running and he said that long-distance runners don't ball strike any more, it's more of a flat landing (so still not heel strike) and then you spring off from your ball. That stopped my feet really hurting after long runs, but as I say I'm still paying the price for pure ball striking.

I only run about 3.5 miles, so that should be good! I didn't know this, thanks for the tip.

(I'd rather have foot pain than knee pain.)
