Just did my third run in my Nike free's. I bought them because I needed some new shoes to last me until December when I start marathon training in earnest and thought I'd give them a bash.
I don't know if it's because I'm getting rapidly fitter, that I ran without music for the first time in years or what, but I absolutely flew home, it wasn't groundbreaking-ly fast (5.5 miles at 8.45 min miles) but it seemed so easy.
I can tell already I'm going to hate 'normal' shoes when I have to go back to them.
Why will you have to go back?
