Alphaflys a bust?

1st and 3rd women in London were in Alphaflys. I don’t think the Alphaflys will work for everyone and that’s probably why Nike is still putting out Next%’s

The are around 1% less economical than the NXT%

You are right - it's the combination of weight and just extra layers of glue and cr@p needed to bond it all together that hurt the shoe. The zoom air bag is not as efficient in terms of resiliency as an equivalent piece of Zoom X foam.

It was a marketing move on and I suspect the only reason it happened so soon after the NXT was because Kipchoge was in shape and ready to go with the breaking 2 attempt. It was the perfect platform to launch it and he delivered.

But bottom line you are right and I can tell you from lab testing - it's simply not a better shoe.

Kipchoge has run one real race in them, and lost

Less comfortable than the Next% (Not that comfort is everything. I would still wear a less comfortable shoe if I believed it were faster.)

Nike hasn't been bragging about studies showing its superiority

Must be a terrible shoe. Nike doesn't seem to want to make them because they are impossible to find anywhere.

I just bought the Next% as many reviews preferred them to the Alphas

they work better for bigger runners or people with a heavier footstrike.

otherwise you aren't putting enough force into the shoe to get the magic back.

I was told from testing it was found to be more economical, but there is an adjustment period for the cushioning. From personal experience it took 3-4 wks to get used to it. My feet and legs feel better in the Alphafly’s than the Vaporfly’s and a 7-10 sec per mi faster pace for exact workouts in the Alphafly’s. Just like any shoe it may depend on the person. The Alphafly’s take time to adapt.

And by then you need another pair.... please.....

No, the Alphafly’s are more durable. They used a thicker rubber on the forefoot and heel, and the cushioning stays springy. I go by heel wear, and I’m getting more wear out of the Alphafly’s than any previous version of Vaporfly’s.

That's a ridiculous statement.

Why is it so unbelievable? @ 6 min pace that would be a gain of c. 2% at the lower bound. Maybe an extreme example but hardly ridiculous.

7-10 seconds per mile is ridiculous 43 to 62 seconds in a 10k? 3-4 minutes in a marathon?

No 1st and 3rd women in London were wearing mango coloured Next%.

Genuinely don't understand why you think this is so ridiculous at non-elite 10k and marathon paces. The shoes make you faster (if your mechanics work with them) - it's not just hype - hence people taking about banning them, records being reset. Runners haven't just improved immeasurably across the board in the last two years.

& note the women slipping in the HM World Champs today were wearing.......

You must be new to running?

Alphaflys are meant to stay good for several hundred miles compared to the 100 miles of Vaporfly and they've got better off-road grip. Great training shoe at the very least.

Going against the general consensus but I actually think they might be better suited to shorter distances, whereas over long distances the extra weight might have more of an impact.

Nah look again. Everyone on the podium had either VF Next% or Adidas Adios Pro.
