Full length Adiprene is ample through the heel and forefoot which provides a firm but supported feeling. Adidas added CMEVA, a compression molded EVA, underneath the Adiprene which really seems to mold to the wearer’s foot and holds up to a great deal of pounding. The Adios 2 is intended for neutral runners and their isn’t any sort of mid foot shank or dual density midsole for added support. However, Adidas did extend the torsion system in the mid foot which decreases twisting and rotation throughout the gait cycle. Arch support is fairly non-existent which is true for most racing flats and Adidas fans will appreciate the traditional fit.
I often get asked to describe what particular cushioning feels like on the road and each shoe company has their different EVA foam which has its own feel. Adiprene is a firmer cushioning which many runners don’t like the feel of when they first put them on. However, it really shines on the road and the Adios 2 is made for long, fast workouts and racing. It also really holds up for many miles which is pretty rare for a racing flat. If you’re the type of runner who does a lot of training in flats and is looking for something to get to that 500 mile mark, the Adios 2 is likely your best bet.
