foot strike - shoes - calf pain

Always run 5k 10k and HM on my forefoot/ toes and farily quickly.

Now stepping up distances and running volume towards Marathon and beyond. Massive problems with calves not liking it. I have given loads of time to build up and done loads of strengthening stuff. The calves are not having it.

One Solution - change to mid strike of foot. But what sort of shoe is best for this? any ideas? Always had Miz Wave Inspire 7/8/9? Do I need more support or less or irrelevent.

Any other solutions welcome?

You can learn to mid foot stike in pretty much any shoe. The only difference that 'flatter lower' shoe is that it helps to get in a better position.

No shoe ever puts you in a strike position, you still have to work on your posture and weight of impact.

I learnt to mid foot strike wearing a pair of Mizuno nexus. (normal suppprt shoes)

Not sure if you can do anything but run miles and miles to strengthen the calves.

I know someone who has had the same problem and he's never managed to get beyond 20 miles before seizing up.

That's payback for the time he gains over shorter distances.
