On the plan of breaking 2, Nike Zoom Vaporfly 4% and Nike Zoom Fly must be the most important 2 pairs of running sneakers of Nike in 2017. Today we want to compare the performance of Nike Zoom Vaporfly 4% and Nike Zoom Fly.

Due to the carbon plate and ZoomX, Nike Zoom Vaporfly 4% became an amazing and unique sneaker. Whether the performance or comfort level, it’s hard to find another running sneaker that can compare with 4%. But ZOOM FLY, the cheaper one, hasn’t given us too much surprise. It just can be a pair of training shoes that has good buffer performance with carbon fiber nylon plate.

The appearance of Nike Zoom Vaporfly 4% is similar to Zoom Fly. The best distinguishing way is to see if the inner hook position has flywire or not.

Most of people may be curious about the sharp prominent design on heelpiece. The designer want to make the shoes look more “sense of speed”. It also design the spade line on both side of insole. The position of carbon plate and nylon plate is almost the same as the outsole rubber, near to the shoe sole.

I’m confused for the size of these two pairs of running sneakers. The size of Vaporfly 4% is a little bigger, Zoom Fly is half size smaller.

The running feeling is totally different, as these two sneakers use different insole material. The insole of Vaporfly 4% is soft and elastic. But Zoom Fly is stiff.
The longest running distance on Vaporfly 4% is 30KM. The speed is between 405 and 420. The tester feel ache on the shank at last 5km and the feet has some bubbles. The heelpiece part of Vaporfly 4% is a little loosing. And the shoelaces were dispersed a few times. But the heelpiece part of Zoom Fly is tight.
Support: 7.5 scores -Zoom Vaporfly 4% vs 7.6 scores -Zoom Fly
If you run slowly, you can only feel zero support from the vamp of Vaporfly 4%. And there is no support on the inner side of arch.

When you wear Vaporfly 4% for 400KM or 20KM for training, you will find that the carbon plate of Vaporfly 4% has great function. The elasticity is great. When your power can’t keep the fast speed, the carbon plate will push you for a few steps.

The support of Zoom Fly is a little better than Vaporfly 4%, the main reason is the insole Lunarlon material is more stiff. One of our tester said the sole of this running shoes is thick and stiff. But you can feel the elasticity if jumping to the grand heavily.
The performance of carbon fabric nylon plate in Zoom Fly is as good as carbon plate.

Buffering: 9.0 scores -Zoom Vaporfly 4% vs 7.8 scores -Zoom Fly
The buffering performance of ZoomX is excellent. The weight is light, and it’s soft. That is the buffering performance of ZoomX. The runner who wears Zoom Vaporfly 4% can get faster recovery time than wearing normal running shoes.

It’s hard to describe the buffering performance of Zoom Fly. The stiff Lunarlon can offer more buffering performance to heavier runners.

After running 18KM, the outside of Zoom Vaporfly 4% heelpiece is abrased. The lateral of insole is covered with a tier of plastic. ZOOM X is covered inside. I’m unsatisfied at the the abrasive resistance of the weak single layer vamp of Vaporfly 4%.

The performance of Vaporfly 4% is still great after running 200KM. The performance of black wear-resisting rubber is great. But it seems that it’s more suitable to run in smooth bituminous concrete. But the outsole of ZOOM FLY doesn’t have big abrasion.

General Performance: 8.2 scores-Zoom Vaporfly 4% vs 7.9 scores -Zoom Fly
After testing Vaporfly 4%, we still can’t define it’s a good or bad shoes. We just feel that it’s a pair of magic shoes. As it use ZoomX, that makes it to be the best buffering running shoes. But meanwhile Vaporfly 4% is also a pair of racing running shoes. The mixing effect of carbon plate and ZoomX make it to be a pair of racing running shoes.

If your training speed can’t reach 4 minutes and 30 seconds per kilometre, it doesn’t need to wear Vaporfly 4%. On the contrary, you can wear Zoom Fly or other light training shoes.
