Everyone makes a super shoe–is there still demand for the Alphafly 4?

Nike’s latest super shoe barely had time to hit the shelves on Thursday before runners snapped it up. The Alphafly 4 sold out within minutes of its release, despite the fact that its wider launch is not scheduled until Oct. 29.

A few years ago, the question for serious runners was whether to race in a super shoe. Now the question is which one. Nike helped define the modern super shoe era, turning carbon plates, high-stack foams and aggressive geometry into the standard. Now every brand makes a super shoe.

So the launch of the Alphafly 4 is less about introducing another super shoe and more about how much demand there is for another one from Nike, the company that helped create the market.

It’s not groundbreaking, but it’s better

The Alphafly 4 doesn’t feature any groundbreaking new features. Rather, it serves as an evolution from the previous model. It still has Nike’s usual forefoot Air Zoom units, a carbon-fibre Flyplate and high-stack foam midsole. But Nike has upgraded almost every component of the shoe.

Nike claims the new version is five per cent lighter, with 10 per cent more energy return. It also features a new version of ZoomX called ZoomX LT, which Nike says is up to 17 per cent lighter than the original ZoomX. The forefoot Air units are also now 30 per cent lighter.

Those improved metrics are exactly what we’d expect from a new version of a super shoe. It’s lighter, bouncier and more responsive than its predecessor. And therefore it perfectly adheres to the formula for a next-generation racer. But Nike is promoting something else that’s not often brought up in the super shoe arms race: stability. We’ll be interested to see if it is more stable at slower paces than the previous version.

Is this a turning point for Nike?

There’s another reason the Alphafly 4’s immediate sellout is notable. The shoe’s launch arrives at a complicated moment for Nike. The brand is set to leave the S&P 100 stock market index on Sept. 21 after nearly 18 years. Although it will remain in the S&P 500, the departure is reflective of the company’s decline in market capitalization.

Although Nike has struggled with business as a whole, running has been a big spot of growth. Nike reported five consecutive quarters of double-digit growth within Nike Running through its 2026 fiscal year. The company also said it gained five points of running footwear market share in Western Europe and North America during the same year.

That makes the Alphafly 4 more than another product launch. It’s a test of whether Nike can turn innovation in performance running into sustained consumer demand. And so far things look surprisingly optimistic. The Alphafly 4 didn’t need much convincing. It sold out right away.

What comes after faster?

This might be where the super shoe arms race is headed. When every major brand can make a fast racing shoe, speed is no longer the differentiator. Consumers want shoes that best fit their running needs.

They want geometry suited to their stride, foam with responsiveness suited to their feet and a carbon-fibre plate that feels fast without too much ankle pain. There are endless options for that now. Nike helped create this very market. Now it has to continue to keep itself relevant within it.
