The Alphafly holds the record for the fastest marathon distance ever. The Alphafly has a carbon fibre plate, super light ZoomX foam and large Zoom Air pods. It will set you back $285.
The Adios Pro is the weapon of choice for some elite Adidas marathon runners. It has a heel carbon plate, Energyrods and bouncy Lightstrike Pro foam. It has a cheaper price of $250.
Which of these flagship super shoes is the right one for you?
The midsole of the Alphafly 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 is made from Adidas’ new formulation of Lightstrike Pro foam which is slightly softer than ZoomX but feels less bouncy. Lightstrike Pro is more resistant to creasing and abrasions than ZoomX.
The carbon plate inside the Alphafly 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 while more flexible in smaller sizes.
The Energyrods inside the midsole of the Adios Pro 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 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 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 has a softer, more cushioned ride which makes it more suited to longer distances because it has more long distance comfort.
The Alphafly has a more responsive ride which makes it more suited to shorter distances. It also weighs less than the Adios Pro which makes it better for shorter distances where every gram counts.
Both shoes have wide forefoot shapes but the Adios Pro has a wider midfoot and rearfoot which makes it more stable than the Alphafly.
The Alphafly uses thicker, more durable rubber on its outsole than the Adios Pro so durability of the Alphafly is higher than the Adios Pro. The Adios Pro has better traction than the Alphafly because its outsole rubber is softer and more tacky.
The upper of the Alphafly is made of Atomknit 3.0 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 a half size small and foot lockdown is excellent. It is a bootie construction so there is no tongue slide.
The upper of the Adios Pro is made mesh 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 fits a half size small and foot lockdown is also fantastic.
If you’re a runner looking for a racing super shoe which is more responsive and lighter, the Alphafly 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 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 softer, the Adios Pro is your shoe. It has a gentle 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.
