THE SHORT ANSWER
The Adizero Adios 6 replaced the Adios 5 in June 2021 and retired the racing flat: stack up to 32/24 mm, Boost gone for Lightstrike Pro over Lightstrike, nearly an ounce heavier, and a $20 price cut to $120 that repriced it as a speed trainer. Race day moved to the Adios Pro; flat loyalists bought up remaining 5s.
At a glance
- The Adizero Adios 6 is 0.8 oz heavier
- 9 mm more heel stack
- Drop moved from 10 mm to 8 mm
- New midsole foam
- List price down $20
Every spec side by side, with the reason behind each change: Adizero Adios 5 vs 6.
Stay on your shoe, or switch?
Changed characterThe shoe was good; the job change was the grief. Believe in the Run titled its review 'The Real Boston?' and argued the 6 took over the lightweight-trainer role the Boston 10 had just vacated, Road Trail Run called the ride snappy and direct yet not harsh, and at $120 nobody faulted the value. What no longer existed, anywhere in the range short of the Adios Pro, was the old low racing flat.
Stick with the Adizero Adios 5 if
- You race in the Adios; the 5 is the last true flat with the Boost heel
- A 10 mm drop is your geometry, the 6 sits at 8
- Weight matters most: the 6 gains nearly an ounce
Old stock is gone; see alternatives below.
Move to the Adizero Adios 6 if
- You want one light shoe for workouts plus fast daily miles
- The 5 beat your legs up past 10K; the 6 has real cushion
- $120 for a Lightstrike Pro shoe is the value pick of the range
Where the Adidas Adizero Adios is now
Four generations separate the Adidas Adizero Adios 5 from the Adizero Adios 9 (2025), so the gap is wider than any single update suggests:
- The Adizero Adios 9 is 1.6 oz lighter
- 5 mm more heel stack
- Drop moved from 10 mm to 7 mm
- New midsole foam
What loyalists said about the update
The market accepted the repositioning: LetsRun threads weigh the 6 against the Takumi Sen for workouts, treating it as the trainer it had become. The mourning ran backward down the line ('no good fast racing flat, ugh', 'bring back whatever adios model the wr was set in'). The small redditrecs sample skews negative, with 'probably too barebones' the representative gripe.

Beyond the Adizero Adios 6, these come closest to what the Adizero Adios 5 did.
- 9 oz
- 6 mm drop
- 36 mm heel
- $160 list
The Boston is where Adidas sends Adios buyers who want more shoe: the same Lightstrike Pro family with EnergyRods, on roughly 9 mm more stack and nearly 3 oz more weight. It inherited the old Adios's training job; it does not replace the ground feel.
Against your Adidas Adizero Adios 5: 1.2 oz heavier, 13 mm more heel stack, 4 mm less drop, $20 more at list.
- 7 oz
- 4 mm drop
- 29 mm heel
- $130 list
The Kinvara is the flat that survived: unplated, featherweight, $130, still low to the ground. It is softer and sits at a 4 mm drop against the Adios 9's 7 mm, but no other covered line shares this much DNA.
Against your Adidas Adizero Adios 5: 0.8 oz lighter, 6 mm more heel stack, 6 mm less drop, $10 less at list.
- 7.9 oz
- 5 mm drop
- 37 mm heel
- $145 list
The Mach answers the same fast-days brief with modern comfort: no plate, supercritical foam, a rockered 37 mm stack. The opposite of ground feel, which is exactly why Adios runners cross-shop it when the flat stops being fun.
Against your Adidas Adizero Adios 5: the same weight, 14 mm more heel stack, 5 mm less drop, $5 more at list.
