A few months ago I received a pair of the adidas Energy Boost. Ran in them a few times and didn't much like them - upper was too tight around the midfoot, too much heel cushion with a lot of flare. They didn't work well with my stride. A few days ago adidas sent along a pair of the adios Boost which looked like a much better match. I'd run in the regular adios 2 before and it was decent, but a bit tight around the toes, so I opted for a half size up in the Boost version.
My quick first impression over 5 miles was very good. The adios Boost reminds me a lot of a slightly stiffer version of the New Balance 1400vs, which I loved. Forefoot is firm, heel soft, and the fit actually is surprisingly good, which I did not expect. Fit is very comparable to the 1400. The heel lift in the adios Boost didn't really bother me, possibly because of the combo of softness and minimal flare.
Looking forward to putting more miles on them!
