Have a medical condition or running-related injury that somehow cleared up when ditching the shoes? Please share!

My arches were hurting a lot when I ran in shoes.  No more arch pain! 

I used to get bad rashes on my feet from crap that they make athletic shoes with. I wanted to run for awhile and researched alernatives to shoes before I got started and discovered Barefoot X's (can't remember who) Barefoot Running website in 2005. I told myself if shoes still gave me rashes I would just do that.

I ended up walking into my local shoe store in 2007 after a surprise baby in 2006 (not a LRS) and I was directed to all-mesh 790s which were just the right shoe for me and I ran successfully in them not really understanding they were particularly minimalist. When I found out 790's were what barefoot runners wore sometimes when not bare, I thought about bare again. In the meantime, my feet went from perfect biomechanics to all kinds of hurt due to a weakness in my ab muscles. I got orthotics in 9/09 and wore them through two halfs. Got really injured (tore my ab clear off the bone) and vowed to start over again bare - I had already convinced hubby to go bare and he liked it and it solved his knee problem. After a few weeks unshod with chiro postural adjustments, the orthotics were torture and podiatrist did a gait scan analysis which was perfect.

I have not had any issues since then. Pure perfection. I do feel like I had an easier transition since I was already in some darn minimalist shoes, including Kilkenny's (I wore them with orthotics eventually) but bare and beach shoes finally strengthened my feet in the right ways. I also healed my ab injury myself - surgery is usually necessary.
