When to return...

You all know by now that I've started training to run a 5K, what you may not know is that I've been training in these bad boys.  

These also happen to be my painting shoes (notice the big pink smear from when I wasn't paying attention and stepped on the paint can lid) and my workin on trailers shoes.  They are getting pretty gross.  I decided, since these are a year old and they are pretty worn out, I should probably get a new pair for what remains of my training program.  I had to go out of town for a doctors appointment and figured while I was there I'd hit up some Kohls action + 15% off.  

I couldn't help myself...I found two pairs.  First a pair of Adidas and one pair of Avia.  My plan was to try each for a bit and then return the pair I liked least.  I ran 1/3 of my run on Annie's treadmill in the Adidas then switched, ran another 1/3 before I decided I liked neither and put on my old beat up tennis shoes and figured I'd try again later.    

On Thursday I ran my full 2 and 1/2 miles in these. 

They rubbed blisters on both my heels.  Not so great.  

Then I ran Saturday in these

Lighter than the Adidas, but not as much spring, only rubbed one heel, but not to the point of blister, just rubbed a little.  A little tight in the toe box (thanks dad for you wide feet).  Now I am not sure what to do.  The Adidas were $50 and the Avia were $30 so the price is not a huge determining factor.  If I were to return a pair, it would be the Adidas...but is that still ok after I ran in them?  I could keep both, it's $80 for two pairs of shoes, not bad really, but do I really need both.  No. But they are both so much nicer than my old shoes.  There's nothing quite like a new pair of tennis shoes. 

Oh new shoes...what to do, what to do.  Return or keep?  What's a girl to do?
