I want to start off by saying that both the Next% and 4% are light years ahead of anything else on the market by "far." When I read reviews elsewhere I found it hard to believe how revolutionary they were until I realized the benefits myself in "substantially" increased performance. I own both the 4% and the Next%. I started with the 4% and found them incredibly comfortable and fit like a soft glove with how the mesh surrounds your foot. The limitation is the durability in terms of life expectancy. I found running on hard terrain tore up the bottoms relatively quickly. But I would trade off the durability and buy additional pairs rather than go back to a lesser shoe. When I moved to the Next% I wondered how much better it could get. I find them faster, more durable and the center of gravity a bit further forward, which seems to provide enhanced performance. It feels unusual though with the tongue material which is like a "flap" and offset of the laces. When I step into the 4% they feel as comfortable as can be and it doesn't get any better. The Next% is a bit uncomfortable and takes getting used to but once running a couple of miles you forget about it. I should clarify uncomfortable as compared to the 4% but still much better than most other shoes. These shoes are worth every penny of the price. I would love to see a combination of technologies of the 4% vaporfly mesh with the foundation of the Next%

These Shoes are amazing, they are the best shoes i have ever run in. i have run in Nike Vaporfly 4%, Nike Pegasus Turbo, Hoka Carbon X, Hoka Clifton's and Brook's Glycerine and Ghosts. I thought the 4% was good but these are incredible, mile after mile my feet keep propelling forward and they are so cushioned my legs are not tired after my runs. I have also had a few PB's and im sure more to come. Pricey but well worth it if your serious about running.

I just got these and just took them for a quick 6 miles. For reference, I did a triathlon the day before and was pretty tired before my run. Meant to go out and run easy which I felt I did but my splits were really fast for a training run. I wasn't even breathing hard and I was close to my race pace for a 10k. Totally effortless strides! As for the shoe construction, they were true to size. Super springy and comfortable. The upper material is super thin but is almost sock like around your foot which is cool being that these are not the flyknit material. The heal has this cool pad that gives you a more locked in feel which is great given the minimalist style of the upper, also adds to the comfort. I am not a fan of the tongue as it is very thin but this is just personal preference for me and does not hinder the performance of the shoe in any way. Cushioning is amazing. Reminds me of the Pegasus Turbo but seems slightly better. Laces are ok. They appear to be the same, cloth/nylon type laces used on the SP's which I am not a huge fan of, mostly because they come untied and I am not usually a double knotter. Overall, the shoe is awesome. I was extremely excited to tell my wife how much I loved the shoes but she wasn't having it, knowing the price tag. Look forward to more colors and getting another pair as well as using them to PR at the Detroit Marathon.
