Not confirmedThis has not been announced by the brand. We publish it as a rumour, not as a fact, and will update the page if it is confirmed.
The Nike Air Zoom Alphafly Next% 4 Proto in Sea Glass and Laser Crimson is expected on 29 October 2026. That date comes from a marketplace listing, not a confirmed Nike launch. One shop lists the pair as of 10 October 2026.
What the colourway tells you
Sea Glass, Laser Crimson, Phantom and Burgundy Ash make up the full colourway. The style code is IU4686-002. Use that code when you search, so you do not land on another Alphafly.
Proto sits in the full name, Nike Air Zoom Alphafly Next% 4 Proto. Nike has used Proto on early Alphafly releases, including the Alphafly 3. It marks a racing shoe inside that family, not a lifestyle colourway.
Where the Alphafly sits
Alphafly is Nike’s road-racing line for the marathon. It is built for race day, not easy daily miles. Runners pick it when they want a light, fast shoe for a long effort.
Earlier Alphafly generations used ZoomX foam, a carbon-fibre plate and Air Zoom units under the forefoot. That mix is the line’s usual build. It is family history, not a spec sheet for this Proto.
The Next% name on earlier Alphafly shoes pointed at Nike’s racing foam and plate setup. Next% 4 is the fourth step in that naming. This listing adds Proto to that name.
Sea Glass reads as a pale green. Laser Crimson is a bright red. Phantom is a light neutral, and Burgundy Ash is a dark red-brown. Those four names are the only colour facts on the listing.
There is no nickname on this pair. Search by the full model name plus the four colour names. That is enough to separate it from a Pegasus or a Vapor that also carries Air Zoom in the name.
The expected 29 October date
As of 10 October, one shop lists 29 October 2026. Treat that day as expected. Check the shop again closer to the date before you plan a buy.
The date is a shop listing, not a Nike announcement. If Nike later sets another day, the shop date can move. Until then, 29 October is the date you can actually see.
