Should I Get More/Less Supported Shoes

Also I should mention that I have fairly flat feet, and my left arch has collapsed more than my right arch.

I would not look to completely change your shoes to something minimal. I would look more at how you are increasing mileage - are you increasing both intensity and volume at the same time? If so, that could be a big culprit.

That said, you might want to try something different. I would, if you can swing it, go to get fit in a new shoe at a good store. Maybe your PT can recommend one. If you are at about 350 miles on your current pair you could throw a new pair into your rotation so you can get a better feel for them but not having to change 100% all at once. Or you could consider an orthotic for your Asics, but be careful as they are a stability shoe and if you add a supportive orthotic it could change things too much. I had that trouble before and got IT band problems.

Good luck.

I used to run in stability shoes and had issues with PF. Almost everyone you talk to, doctors, PTs, shoe store staff, will tell you that you need MORE support.

I went to a neutral shoe and I no longer have PF issues. I generally run in a neutral light weight trainer. I don't have a specific brand or model as I have had Mizunos, Saucany, Brooks etc... Just no stability shoes.

It is worth a try as it only costs a pair of shoes.

Regarding the increasing intensity and volume, I got the injury only four days after starting summer training. So I guess maybe in regards to the volume, but definitely not in intensity. Also I only took a week off between track and summer training, and while the end of track season I wasn't running too much I was still running.

If you want to look at what I've been doing, I think you should be able to look at my strava log:

Nah man. I don't think stability shoes/support shoes help anything. I would stick with something completely neutral and regular. As others have said, it's probably mileage or form or something. The reason why plantar fasciitis is usually cured (at least for some) by maybe a drop in heel-toe offset and minimal shoes is because those people are inadvertently strengthen thing their calves. I would suggest just doing strengthening.

As for what I think about minimalist vs. supported.. I am a fan of a mix. One of my favorite shoes of all time is the Saucony Kinvara - a shoe that is really lightweight but at the same time not completely minimal. Unfortunately due to arch problems, I'm not able to wear these anymore. I'm a big fan of a light shoe though. I currently wear the Pegasus, but it is far from my ideal shoe. It gets the job done and that's all I really care about. I would veer away from any form of actual minimalism though. I know many that have gotten injuries from things like NB Minimus, etc.

There is little or no science that arch support and cushioning will reduce injuries.
