Running woes...

Go to a propper running store (as opposed to somwhere like Walmart) and get fitted for a pair of running shoes -  shoes that are right for your feet etc

The right shoes will make all the difference

Wear good running socks - consider body glide

Just my opinion.  I also suffered from some blisters and thought I would get them again.  As it turns out my feet have hardened over time and now I no longer get the same painful blisters.  Sometimes I'll get one, but they don't hurt anymore.  Good luck and don't worry about it.  Your body will adapt.

I can't wear my thinner running (or cycling) socks on anything over 30ish mins or I'll get a blister. You might just need different socks. And the area with the bad blister, probably won't get another one. Did it form a callus?

I've had problems with blisters for a few years. The kind you had do take a very long time to heal. Two thing I've done this year have completely eliminated all blisters. 1. Injinji socks - amazingly effective on their own. 2. Rub my feet all over with an antiperspirant to keep them dry. I've found this is much better than Bodyglide.

I've tried a bunch of different kinds of socks over the past several years and none has been as effective as Injinji.

Thank you, what series do you use? The Performance series? 

Yes, the Performance series. They feel wierd the first time, but after a mile they feel like any other sock, except there are no blisters.
