Again, the video is slightly impressive and I agree boost tech is appealing because of bounce/comfort but I don't think it outperforms lunarlon in the metric that is set where durability, weight, structure and 'cushioning in ratio to responsiveness' are key factors.
Sure it may be "more comfy" in regards to walking around the mall and more lifestyle settings but further than that I don't think it lives up to the hype. Boost tech is a very comfortable foam and you get a sense of gratification when you first wear it but it doesn't compare to lunarlon, vapormax, air max, or even vulcanized rubber solely (no pun intended) because of the performance aspects of the shoe as opposed to just comfort. When it comes to comfort I agree the ub and even the 9317 model are a step up for comfortable walking but when it comes to performance I believe they fall far behind. The shoe is heavier, the primeknit may be softer to the touch than flyknit which gives the impression that its "more comfortable" but its actually stretchy and non reliable if you ask me. The boost may be more "responsive" but its less durable than vapormax which is just as springy. Just doesn't add up, hype isn't enough to catch up to decades of innovation
If I had to run for my life I wouldn't pick a yeezy nor an ub. It would be an flyknit or an airmax lol
