Nu Shooz

Broke in the Nike trainers which I bought yesterday. As always with a new pair of shoes, they felt a little strange after the Adidas shoes I've been running with for the past year almost.  Still, they took me to ten km in one hour and one minute with no discomfort so that was alright. Now, the question is, should I wear these trainers for the ultramarathon or the Under Armour Speedforms which, although they took me to my fastest marathon time ever a few months ago, also gave me blisters? These Nike trainers are not so expensive or hi-tech as the Speedform trainers, but they may be more comfortable and I am not in the ultramarathon for speed.

Suggestions from any runners out there are most welcome.

I am very happy with the serendipitous rainbow whoosh in this photo. Did the Nikes do this do you think?
