The Nike Alphafly Next% 2 is a super shoe which was designed for narrow-footed runners and runners with high arches because it has a very narrow midfoot. It’s best suited to short, fast-paced workouts rather than long runs because of its firmer ride and prominent arch. This version has been updated with a new, snugger Atomknit 2 upper, a more durable, flatter outsole and a wider, more stable midsole.
The Adidas Adizero Adios Pro 3 is a long-distance specialist. Its highly cushioned midsole and its efficient, energy saving ride make it perfect for marathons and beyond. Version 3 has more foam in the forefoot, a wider net base and a more aggressive toe-spring which makes it softer, more stable and more propulsive than the previous version.

Sole unit: Zoom Alphafly Next% 2 vs Adizero Adios Pro 3

The midsole of the Alphafly 2 is made from ZoomX which is Nike’s lightest, most responsive midsole foam. ZoomX is cushioned at slower paces and springy at faster ones. The one downside to ZoomX is that it doesn’t have great durability and tends to compress faster than other midsole foams over time.

The midsole of the Adios Pro 3 is made from Adidas’ Lightstrike Pro foam which is slightly heavier than ZoomX but feels denser and more cushioned. Lightstrike Pro is more resistant to creasing and abrasions than ZoomX.

The carbon plate inside the Alphafly 2 has a slight curve and works in the same way that a lever launches you forward when the front is anchored.

The carbon plate is stiffer and bigger in larger sizes of the Alphafly 2 while more flexible in smaller sizes.

The Energyrods inside the midsole of the Adios Pro 3 are spread out and mimic the metatarsals of the foot. They keep the shoe stiff and give structure to the shoe.

Propulsion in the Adios Pro 3 is created by the tipping sensation which comes from the high toe spring and rocker.

The biggest difference between the midsoles of the two super shoes is that the Alphafly 2 has forefoot Zoom Air pods which provide extra propulsion on toe offs. The harder you strike and compress the air unit, the more energy return you get.

The Adios Pro 3 has a softer, more cushioned ride which makes it more suited to longer distances because it has more long distance comfort.

The Alphafly 2 has a more responsive ride which makes it more suited to shorter distances. It also weighs less than the Adios Pro 3 which makes it better for shorter distances where every gram counts.

Both shoes have wide forefoot shapes but the Adios Pro 3 has a wider midfoot and rearfoot which makes it more stable than the Alphafly 2.

Transitions are smoother in the Adios Pro 3 because its outsole is full contact and there are no air pods which results in a more fluid, seamless ride.

The Alphafly 2 uses thicker, more durable rubber on its outsole than the Adios Pro 3 so durability of the Alphafly is higher than the Adios Pro 3. The Adios Pro 3 has better traction than the Alphafly because its outsole rubber is softer and more tacky.

Upper unit: Zoom Alphafly Next% 2 vs Adizero Adios Pro 3

The upper of the Alphafly 2 is made of Atomknit 2.0 which is steamed and stretched to create a porous but light material. It feels a bit rough to the touch but it doesn’t absorb any liquid so it stays light during runs. It fits true to size and foot lockdown is excellent. It is a bootie construction so there is no tongue slide.

The upper of the Adios Pro 3 is made of Celarmesh which is smooth to the touch but not as breathable as the Alphafly’s upper. The tongue is not gusseted but sewn onto the eyestay so it doesn’t slide sideways during runs. The Adios Pro 3 fits true to size and foot lockdown is also fantastic.

Which one to buy: Zoom Alphafly Next% 2 vs Adizero Adios Pro 3

If you’re a runner looking for a racing super shoe which is more responsive and lighter, the Alphafly 2 is the shoe for you. Its forefoot Zoom Air pods provide an explosive toe off while its carbon plate propels you forward. It costs more than the Adios Pro 3 but it has a more comfortable upper with a more durable outsole.

If you’re a runner looking for a racing super shoe which is more cushioned and more stable, the Adios Pro 3 is your shoe. It has an extreme rocker which propels you forward and super smooth ride transitions. It is better value for money than the Alphafly but it has thinner outsole rubber which will wear down faster.
