As a teen at the age of 17 I decided to buy my first "racer" classed shoe, this being the shoe I bought and to be honest the shoe it self exceeded all expectations.

My initial reaction to this fantastic shoe was "Wow, so light", and "really awesome looking", and once I took this beauty to training I realised the pro's and cons to the shoe.

Pro's, light weight, suitable to 5km to maybe 10km for those weighing in under the 70-80 kg being the max(myself weighing in at 56kg) and superior breathablility, never had anything like it!

Con's- Being so light and having only the minimal materials does mean that there is little support for distances over the 10km barrier...(I haven't tried myself but, 8km starts having its toll on me)

My conclusion is that the Adizero pro is perfect for light weight runner looking for the edge on the competition, a must buy.

Fantastic racer. I only use it for interval training and 5k road races and at short triathlons. Great traction, too. Do go fot it if you weigh more the 75kg, the cushion is designed indeed fore lighter runners.
