Completely different shoes (I have the Adizero Pro & Adios Pro 2).
I've put 300+ miles on my Adizero Pro, used them for most of my speedwork during London marathon training, and a couple of 5/10k races. I really liked them. Just an old school lightweight flat in honesty (which I like). They were a bit "slappy" at first and as such I didn't take to them right away, but once they'd mellowed/stretched slightly I really enjoyed going fast in them. Fast feeling, smooth running shoe. Saying that, I did suffer from their lack of arch support somewhat, and have now retired them.
Adios Pro 2 are vastly different. I like these too! They'll definitely be my shoe for London. Incomparable to the Adizero Pro, though....different foam, ride, bounce etc. Quite an aggressive shoe, this. You really don't want to go slow in it, but once moving along, the bounce/energy return feels like an underfoot po-go stick! Much less mushy than a Vaporfly, and very much promotes getting "up on the toes" which I find Adidas racers do in general. I feel like this shoe could go fast over pretty much any distance, but it's not stable enough for anything other than smooth roads, though the grip is excellent. The only downside I have is that the fit is a little tricky to get right, and I've ended up with a blister on the medial upper foot, near where the last couple of lace eyelets are. Easily solved with a plaster, but you've got to keep the fit snug to get the best out of it.
