I'm 100% a Nike fan. Hands down, their best shoe is the Nike Free Run+ 2 ... I've owned 4 pairs. Currently I have 3 pairs that I use on a weekly basis. Why have 3 pairs of the same shoes, let me explain.
My oldest pair are the ones I used to train for my half marathon... they were toast by the end of the race/training. I now use them for going to lift weights or spin classes.
The other two pairs I rotate. I'm new to this whole rotating process, maybe I'll explain that in another running post. Anyways, I alternate which ones I run in, in hopes of prolonging the life of my shoes.
I'll leave you with some words from a friend that took my advice on switching shoes :) "thank you sooooo much for getting back to me so quick! Your suggestion is amazing and I absolutely bought a pair. Ran in them for the first time today and absolutely fell in love!! They are just as amazing as you made them out to be. So thanks pretty lady!" Sybil
**You can get the +2 versions a lot less at sites like 6pm.com, zappos.com and amazon.com. Nike.com currently only sells the 3, 4 and 5 versions.
