Good! So I'm writing this to say the good and the bad. Pros: This new FF BLAST technology is one of the best I've used, way better than On Cloud, Nike Reaction and equal or slightly better than the Ultraboost 20, moooooo better than all Mizuno and Saucony shoes, the midsole is too stable, even if you step too far to the right or left, the shoe will try to keep the foot centered. I think the midsole and FF Blast technology is 10 out of 10. Cons: Shoe construction, webbing and sidewalls are just loose, I think something big, no sign of fit or stretch technology anywhere, and the feeling that the shoe conveys "loose" I guess it doesn't matter if you speed sessions, fartleks etc but I used them in a half marathon today and they feel big/loose if you are used to wearing shoes like the Ultraboost, Nova Boost, NB 1080 etc. They will feel feel different and uncomfortable. General comment: From my personal point of view. 3 out of 5 is fair. The midsole is the highest point, stable, soft yet durable, cushioning and resilient, just amazing. But the "lattice" is uncomfortable, doesn't fit at all, it looks loose and large. I recommend not using them for more than 1:30:00 hours, 10km to 21km, definitely not for longer distances like a marathon. The price is acceptable.
