<human>: Can you succinctly summarize the text in 1-3 sentences?

Hey guys, I did a lot of googling and searching on here first, but I'm not sure if what I found answers my specific question/problem.  If anyone with more experience has advice, that'd be great!

Been running for about two months, gradually increasing to about 20 miles/week, 2-5 mile runs each day, about 6 days/week.  I was running in a friends old running shoes for the first month and a half.  They felt OK - I didn't have any injuries or pain except one spot that rubbed on my right arch.  

Two weeks ago I bought [these] new running shoes.  I wore them just walking and biking around, and for 2 mile runs for the first couple days, and they felt great.  Then, taking them out on 3-5 mile runs, big arch troubles.  Around mile 3, I gradually start to get painful cramps along both arches, more toward the balls of my feet than the heels.  I tried stopping and stretching my calves and rubbing my feet, which would make them feel fine until I started running again, then the pain was back.  This happened on 3 runs in a row, where I had to stop and walk home.  I bought some Dr Schols arch support inserts, and they didn't help at all.  I tried just running through the pain (w/ inserts) yesterday and it was totally awful, even walking hurt for a little while afterwards (though about 30 minutes after, everything feels fine again).  

Today I ran in the old running shoes (ASICS, I can't find a link though) and got the same cramps/pains but a quite a bit milder, though I was taking it a bit easy.  

Is this just a matter of getting different inserts?  New shoes?  Shitty form?  Or I'm injured and need rest?  Thanks for your expertise, r/running.
<bot>: New runner jogs in friends old running shoes- pain free.  Buys new Mizunos and develops very intense arch pain toward the balls of both feet, during runs only.  Drugstore arch inserts do no good.
