The MOST COMFORTABLE sneaker I’ve ever worn! I’m a sneaker/kicks fanatic and these are worth Every Cent! Bought 2 pairs- one every day and one for nicer occasions. Wear with everything. Even with business attire ✅

One of the best running shoes I have owned. Adidas Ultraboost was recommended and highly raved about among our friends but could never justified the price until I owned it. It is extremely light and fit your feet like a sock.

Super comfy and supportive, also stylish can wear with everyday clothes or joggers. Takes impact very well when running. Excellently Crafted Shoe.

For the price, they are OK. The outer soles are almost worn flat at the forefoot area. The insoles had a lot of pet hair on them. Had to get replacements. Next time would just spend a little more and get a product not so worn.
These shoes are great lifestyle shoes, but as many others have mentioned, not great running shoes. They're incredibly comfortable and the boost material is really like nothing else out there, but the stability of the shoes when running is lacking. There's no support when you push this shoe to the limit. However, for speed walking or wearing this as a "sneaker", there's nothing else more comfortable. Highly recommend as a lifestyle "sneaker".
Very happy with these sneakers. They are super comfortable, fit me just right. And I've gotten several compliments about them too. Will definitely buy these again.
So amazingly comfortable! My new favorites, and super cute. Have received many compliments. It matches nearly all outfits.
Fabulous pair of sneakers, I've only had a few short runs in them yet but they are very comfortable & fit my foot perfectly. Fit true to size. Hoping they won't end up looking dirty & dusty!
The new updated version of the ultraboost is very comfortable and good for those with wide feet. However, if you are looking for a snug for running shoe then these won't be for you. The primeknit upper is thinner and looser than previous versions.
I bought pair of these shoes for my son for his 14th birthday. They arrived with the plastic retail security pin still attached to the shoe. Thankfully I opened my sons birthday gift a few days beforehand and was able to take the pair to a local sporting goods store to have this removed. I emailed the company about this and never got the courtesy of a response. Will not make the same mistake of shopping here again.
