Lightweight but substantial enough midsole where it works as an everyday trainer

I have used the Adios since Adidas has launched them. This is my 3rd pair of the shoes. I like the way they feel under my foot, or the responsiveness of them. I like how they have some cushioning but not a whole lot in the forefoot. Whenever I wear the Adios I feel as though my gait is more fluid and in turn makes my runs that much better and smooth.

I really enjoy this shoe. I ran in Kinvara's, and the Virrata's (both saucony) and liked them. But, this shoe was the one with the most pop behind it. It made me feel like I went from running in a minimal shoe, but could transition into speed work in the shoes easily.

I bought the shoe to race in, for a 30k specifically, but it's been so comfortable I train in them every day. I thought they'd be too thin and hurt my feet but the foam is both firm and easy on the feet. Remarkable.
