The Nike Vaporfly is the original super shoe and the most popular racer. It's such a popular racer because of its wide availability, its low weight and its high level of speed assistance.
Version 2 was only an upper update but version 3 is a complete revamp. Which version is better for you?
Both versions use Nike’s premier midsole foam, ZoomX but the midsole of the Vaporfly 3 feels softer than the Vaporfly 2. The Vaporfly 3 has more cushioning under the forefoot and it has a plusher ride than the Vaporfly 2.
The Vaporfly 2 feels faster because of its firmer ride whereas the Vaporfly 3 has more long-distance comfort. The Vaporfly 3 is geared more towards marathons but the Vaporfly 2 performs better in shorter races.
The Vaporfly 2 has a more aggressive toe-spring than the Vaporfly 3 so it has a more prominent forefoot rocker. You can feel a higher level of speed assistance in the Vaporfly 2 compared to the 3.
Stability is better in the Vaporfly 3 due to its wider base. If you need more stability, the Vaporfly 3 is the better option.
On the outsoles, the Vaporfly 3 has less rubber than the Vaporfly 2. The rubber is thinner and less durable. The middle of the outsole of the Vaporfly 3 also scuffs much easier so the Vaporfly 2 outsole will outlast the Vaporfly 3.
The upper of the Vaporfly 3 feels more refined and more comfortable than the upper of the Vaporfly 2. It’s more accommodating in the midfoot and forefoot so it fits more like a trainer than a racer.
The toe-box of the Vaporfly 3 has big holes in it which the Vaporfly 2 doesn’t. This makes it more breathable and better for racing.
The ankle area of the Vaporfly 3 conforms to the foot better and there aren’t large gaps around the ankle like in the Vaporfly 2. Both racers fit true to size.
If you’re looking for a short distance racer and you don’t need much stability, get the Vaporfly 2. It feels leaner and faster than the Vaporfly 3.
If you are looking for a long-distance racer, get the Vaporfly 3. It’s more comfortable and has more cushioning.
The two racers weigh almost exactly the same so your decision should be based on what you will be using it for.
