All have a narrow midfoot, which I find feels like a straight jacket around the foot causing pain, but a lot of people love these shoes. They certainly look great.

Alphaflys: amazing bounce, feel better when running fast with good form but once tired feel sloppy. Have had a few pbs in them, until I get the midfoot pain.

Tempos: soo noisy. Nice but gave me knee pain as too much cushioning can cause instability. But they strengthened glutes and gave me a few pbs yet again which great, but had to return due to knees hurting every time I wore these.

Vaporflys: loved these until my midfoot just couldn't take the narrowness if the midfoot anymore.

Those with normal feet will love these shoes, unfortunately I'm not one of those. Out of the three, the Vaporflys will probably last longer, give that forward propulsion feel, still mega light & not noisy, just wish they were wider midfoot and didn't taper in so much.

Toe room in all three is roomy.
Lockdown is good, some might say the upper can strangle the foot too much if you have high volume to your foot as you dorseflex.
