I am loving these shoes. I’m training for my first half marathon and these are a game changer! I saw a recommendation to order a half size up so I did and would recommend it!

If you haven’t run in the alphafly 3 or vaporfly 3 and you’re over 50 you’re missing something
Nike User - 06 Jun 2025
An amazing shoe! Love the vapor fly 3s but have a little bit more support and I’m coming back from a small injury and appreciating them. If you haven’t run in the alpha fly or a vapor fly three and you’re a If you haven’t run in the alpha fly or a vapor fly three and you’re an older runner. I’m in my mid 50s. You should pick up a pair. You’ll run faster and you’ll be less tweaking with the foam and they’re just plain fun.They’re beautiful they run true to size. The photo is from a Sprint session. I did recently in another pair of Nike track bikes.
Very poor quality, but they are comfortable and supportive

Do not purchase, the quality is very poor. I received and tested them on my block. Although they are very comfortable and look reach nice the back flap came apart. Also the sides were worn in just wearing them for that block. For the price, these are not worth it at all unfortunately. I really looked forward to these because they feel so good, but they won't last.
