I've got a brand new pair of Adidas Adizero Adios running shoes. I call them the Geb shoes, because Haile Gebrselassie can run very fast with them. For example, he set the marathon World Record 2:03:59 last year in Berlin.
In the video below Geb runs four minute miles on a treadmill. That's much faster than his marathon (or half-marathon) race pace. His running style seems very smooth, there's no sound from the shoes. AAA is an excellent racing flat in every way.
Except the distracting yellow/black/silver/white color scheme, of course. Luckily these new models are black/yellow/silver/white, which makes all the difference to me. They look pretty cool IMHO, considering I've already trained a fortnight without cleaning them.
As far as I know they are pretty much the same in every other aspect. I upgraded sizes from US 10.5 to US 11.0, but they are still ultralight: 219 grams per shoe.
Due to my personal preference and also the location of my home I run mostly on dirt roads. I don't want my shoes to collect too much dirt. Therefore outsole design is a matter of the utmost importance.
These shoes are one of the best I've seen regarding the outsole design. Well done Adidas!
I plan to run a half marathon on dirt in September and a full marathon on asphalt in October with Adidas Adizero Adios. I'll put these shoes - as well myself - to a tough test on both occasions.
