adidas Adizero Adios 7 Review: Speedy
By Senior Contributor David Salas

The Adidas Adios line traditionally has been the racing shoe in the 3 stripe lineup up until recently. Now with the addition of the Adizero Adios Pro series the Adios series has become more of a performance trainer or training companion. The Adios 7 continues the speedy trainer (and potential racer) line with a light weight responsive package. The firmer and snappier platform is combined with a nice bouncy Lightstrike Pro midsole in the midfoot and forefoot.

RUNNING SHOE SUMMARY

The Adidas Adizero Adios 7 is a performance trainer that has a relatively firmer and flatter profile built for speed work. The shoe has good traction underfoot and uses the traditional torsion system familiar to the series. The shoe uses a firmer Lightstrike midsole full length with nice amount of the bouncy Lightstrike Pro in the midfoot and forefoot. The Adios is a versatile performance trainer that can tackle fast paces and keep miles off of your special day shoes.

FIT


The Adidas Adios 7 fits true to size in my normal Men's 9.5, though I think you could argue sizing down a half size due to length. The shoe fits similar to most Adidas performance shoes for me, being a little on the long side and a little more narrow through the midfoot. The tongue is lightly padded and lets me lock the shoe down a little bit tighter. I did have a little bit of heel slippage initially and used some of the additional eyelets to help with locking the shoe down a little bit better for me. The mesh material itself is very airy and decently comfortable. The volume through the shoe is a little lower and is consistent with that performance lock down fit in many speed shoes. There isn't a specific heel counter in the shoe but there is some slightly thicker material that lines midline of the calcaneus and like guide wires medially and laterally to help maintain the structure of that region. There is some suede overlay in the forefoot that seems to hold the structure pretty well too. Overall, the shoe itself is slightly long, but otherwise features a well-done performance upper. 



PERFORMANCE

The Adidas Adizero Adios 7 is a performance trainer that likes to get things moving. The platform and geometry is a little flatter and not the big rocker design you are seeing in a lot of long distance racing shoes. The geometry lends itself to turning over fast and using your mechanics to drive the shoe. The shoe uses a dual density midsole with a firmer Lightstrike midsole through the full length of the shoe and the really soft and bouncy Lightstrike Pro through the midfoot and forefoot. The shoe has a lot of traction underfoot and gives you a good grippy platform to drive from. The shoe also uses the traditional torsion system (plastic shank) that extends from the distal rearfoot through the forefoot in a prong like motion as the shank blends with the medial and lateral aspects in the forefoot. This creates a firmer and snappier ride underfoot. On road conditions the shoe does feel a little rigid and "slappy" at easier paces but feels really smooth and responsive when running fast. The Lightstrike Pro really comes alive when you start entering tempo or interval pacing. There is a slight posterior lateral bevel that helps with easing the initial contact though it is not very dramatic. The shoe feels like it fits the traditional flat profile a little more and feels good at speeds. At easier paces it does ease up and feel less "slappy" when running in dirt or grass though. For me, this firm riding snappy performance trainer is a solid option for workout day whenever you want to run fast.

STABILITY


The Adidas Adizero Adios 7 is a pretty stable shoe for the category. The foam and platform is on the firmer side and blends well with the great Continental traction underfoot. The platform itself is a little more narrow and speed driven which does make the area underfoot a little less stable especially through the midfoot at easier paces. The torsion system does seem to provide enough rigidity to help with though. The torsion system prong design in the forefoot also helps with giving a solid trustworthy forefoot platform while still maintaining some softness or cushion in the midline of the shoe. The upper security is pretty good throughout once it is locked down with a solid lacing. The length creates a little room in the heel so I did need to use one of the additional eyelets to lock the shoe down more. The shoe has performed quite well for me in nearly any footing reasonable enough for a performance shoe or workouts. Outside of the foot movement due to length before locking it down the stability is pretty good. 



THOUGHTS AS A DPT / FOOTWEAR SCIENCE

Why are many performance trainers and speed dependent shoes so stiff? This can be for a lot of reasons. When a platform has a little more rigidity and longitudinal bending stiffness the shoe will be harder to bend. Under greater forces and flex points the materials in the shoe will flex and provide a popping or bouncing sensation forward. In many ways a plate or stiffening agent will act more as a lever than it will a spring (Hoogkamer, Kipp, & Kram, 2019). Increasing a lever arm under a greater amount of force will normally increase force output, though there is a lot of other factors that may influence this. Day & Hahn (2019) studied the effects of longitudinal bending stiffness on running economy and subjective comfort at varying speeds. They found that runners would show economic improvements in stiffer shoes compared to normal shoes at 17km/hr as compared to 14km/hr, despite the stiffer shoe being slightly heavier. Subjectively it was shown that the stiffer shoe was also more comfortable than the normal shoe at these higher speeds. There are a lot of factors that go into what makes a shoe pop, though one element that seems to be common and something worth looking at is longitudinal bending stiffness.

RECOMMENDATIONS

I think the big thing to work on with the Adios 7 is the lockdown of the heel. I didn't have any problems with foot translation medially or laterally at any point, though I did have heel slippage. Once I used some of the additional eyelets and lace the shoe down tight then I did ok. I think cleaning up the length or heel security would be the best move as the other components of the shoe perform quite well. 

WHO THIS SHOE IS FOR

The Adidas Adizero Adios 7 is a firmer riding performance trainer that really knows how to turn over when loaded. The shoe can be a little less smooth at slower paces especially on road conditions, though does okay in dirt and grass. The snappiness of the shoe really comes alive in workout and speedier efforts. Those that don't mind a little length on the shoe and like a snug fit throughout this is a solid performance trainer and training companion.


GRADING

David
Fit: (Good volume and snug fit throughout with good security through the midfoot and forefoot. Length issue being a little long required some lacing modifications.)
Performance: B+/
A- (Very responsive performance trainer that is a little firmer riding. Not as smooth at easy paces but can get it done for warm up and cool down.)
Stability: A- (The upper fitting with length created a small amount of translation, though otherwise is pretty solid with feeling secure on platform and traction)
DPT/Footwear Science: A- (A solid integration of new generation materials with a more traditional speed design without a plate)
Personal: A- (A shoe that is really fun to run fast and workout in. It is a little firmer and slappy at slower paces so this is really a workout day shoe for me exclusively.)
Overall: B+/A- (A solid performance trainer with some blends of new and traditional. A firm and snappy shoe that requires a little bit of lockdown with the upper.)

***Disclaimer: These shoes were provided free of charge in exchange for a review.  We thank the people at Adidas and Running Warehouse for sending us a pair.  This in no way affected the honesty of this review. 
We systematically put each type of shoe through certain runs prior to review. For trainers and performance trainers, we take them on daily runs, workouts, recovery runs and a long run prior to review (often accumulating anywhere from 20-50 miles in the process). For racing flats we ensure that we have completed intervals, a tempo or steady state run as well as a warm-up and cool down in each pair prior to review. This systematic process is to ensure that we have experience with each shoe in a large variety of conditions to provide expansive and thorough reviews for the public and for companies. Our views are based on our extensive history in the footwear industry and years testing and developing footwear. If you are a footwear rep looking for footwear reviews or consultations on development, we are currently looking to partner with companies to assist, discuss and promote footwear models. Partnership will not affect the honesty of our reviews.
