My first impressions of the adidias adiZero adios Boost after a 10K test run are overwhelming positive.
The adios Boost is built like a racing flat. It has a secure fit in the heel through mid-foot, with a more relaxed fit in the forefoot, which is unusual for shoes in this category. This gives gives a bit of room for the toes to wiggle and allows for a more natural landing (despite the stiffness issue I discuss below). While the 9mm heel lift was noticeable to me standing around—and after I returned to my 4mm Brooks—once I started running it didn’t bother me at all.
The fit worked great for me, even though I went with a 1/2 size smaller that I usually wear. I seem to be the odd man out in this, as most reviewers went a 1/2 size larger. This could be because the upper material is nice and forgiving. It could also be because my test run was only 10K on a cool day, so my feet weren’t swelling.
To be honest, I didn’t notice any difference with the Boost technology vs the EVA of other running shoes. This could be due to my a quicker, forefront stride, as the Boost technology is concentrated in the heel and aimed at the larger market of heel-strikers. The forefoot is firm yet supportive. The heel is comfortable soft, without being musky.
About the only criticism I had of the adidias adiZero adios Boost is the stiff forefront sole. During the run, I felt like I was slapping the ground with my forefoot. This is quite different with the ‘natural’ running form that shoes like my Skechers GOrun’s promote. I’ve read other reviews mention the same issue. However, as the shoe is intended for racing and faster workouts, the stiffness isn’t necessarily an undesirable feature. Indeed, I expect that it would make for a very responsive racing flat.
Based on first impressions and limited mileage, the adidias adiZero adios Boost is definitely a contender for my next trainer. I’m not sure it is ‘enough shoe’ for me to tackle a full marathon, and the forefoot stiffness is a bit of a concern, however, I think the light weight and firm but supportive forefront make it a great shoe for races up the half-marathon, as well as faster workouts.
