Stability is better in the Alphafly Next% 2 because it has less lean bias and is a more stable platform compared to the Alphafly Next Nature.
Both super shoes have giant Zoom Air units in the forefoot which provide extra pop on toe-off. The faster you run, the more the air units compress and propel you forward.
There are full-length carbon plates in both shoes but the one in the Nature version is made of 80% recycled carbon fibre. Both carbon plates are extremely stiff and assist in making the rocker more effective.
