<human>: Give me a shortened version of the text

So I did that thing where I took up running with the thought that I just needed a pair of shoes and could go run to my heart's content. After 20km over my first month, I thought I was going well so I did 80km over the next month. Ankles started hurting, went to the doc, turned out I'm extremely flat footed and ran in shoes with virtually no support which eventually killed both my ankles. I stopped running for 1.5 months to rest up and recently started again three weeks ago. I got some new shoes with a lot of support but now I get blisters (never had blisters before) around my right arch and my ankles don't seem to be getting any better. I also saw my City2Surf finishing video and I still run weird. Is this just another "give it time" thing or am I doing something wrong?
<bot>: I have flat feet. I ran on shoes with no support for 2 months and did some damage. Rested up. Got new shoes. Doesn't seem any better. Help?
