First pair of Ultra Boost. Own a pair of Prime Boost, but upper design and insole is very different. Product arrived on time, although box was badly damaged, I have a plastic drop front boxes for my higher end shoes, so that wasn't so much of a problem. If it were Jordans, then it would be an big issue. Overall, like the shoe very much. Extremely comfortable, not sure about most comfortable ever, but close.First time trying the ultra boost and they are extremely comfortable. I mainly use them for the gym but they are great to walk around in. I waited till they were at a reasonable price before I purchased. &200+ for sneakers is a little much when I go through them so fastI liked itThese shoes are extremely comfortable and I just had to get a second pair! You can’t go wrong with these shoes.Great, authentic shoes! I should never have waited to buy. They are so comfortable!Completly doesn't work brush just ruins your shoeI used on ultra boost all whiteThe plastic lace hole cracked only wore 12 times
