I bought a pair of these traininers about a month ago and my verdict on these is that you can notice a big difference from my old Brooks Ravenna 3 but personally there not worth the price and i think i was just taken in by the media hype. They are very soft and extremley light and they do offer brilliant support without having to have a bulky trainer but personally i was i had gone with the new Kayano 19.
Are you sure you got the adizero adios Boost? As gazhowell said, it would be odd to compare a lightweight marathon shoe with an Asics support shoe with a massive heel.
The skull motif is the Nike Oregon Project (where Farah trains under Salazar) logo, you can get Nike t-shirts with it on.
As for the gold trimmed vest, Stephen Kiprotich was also wearing it, so I'm guessing it's the kit Nike sponsored athletes who won golds at the Olympics will be wearing this year, but not on general sale.
