hello I bought my ultraboosts for 200 dollars. Everything is awesome except for the priceif this review helped you please mark this review as helpfulComfort- These shoes are like sitting on clouds. they feel awesome and hug your feet. They feel tight enough to stay on when running but lose enough to be comfortable.These shoes far out-class many another running shoeDesign- the design is ok but nothing special. The gray ( the one that I bought) are much less gray in person and look decent. The white part looks kind of like styrofoam and the heel cap looks good. The heel cap has "ultraboost" on it.you can easily tell its Adidas.durability - these shoes are not the toughest. the white bottom gets dirty super easy and does not clean easily. I noticed that the shoe rubber bottom start to come off. The Adidas cage on the side of the shoe gets scratched super easily.Value- these shoes are 200 dollars. The look pretty good and are great running shoes But they break really easily. If 200$ laying around go ahead and buy these shoes. but keep them safe and try to use them carefullyIf this review helped you please mark this as helpfull.Had over a year, everyday shoe. Like your walking on a cloud. Ran a marathon in them, didn’t help me win but looked good. HaStarted training to run a marathon with my brother in 2018! Bought these for him on Christmas and he loved them! He is a size 10 in athletic shoes and I ordered him a size 10 and they fit perfect. Says they are really comfy and great to run in. I might have to buy myself a pair soon to try them out myself. Don't really know how they'll keep up but i'll as soon as they give out.I own multiple Ultra Boost 3.0s and 4.0s and all I have to say is that they’re both very comfortable but they definitely run different in size. I wear a 9 in the 3.0s and and 9.5 in the 4.0s and they feel exactly the same. Trust me the 4.0s do run shorter than the 3.0s. So make sure you get your right size and enjoy walking on air.I was thinking that I would wear a pair of thin no show or ankle socks with these, but they seem a bit small with socks. I am thinking they may stretch, but so far no sign of that happening. They are actually so comfortable, and breath well ... you don't need socks. They are the best shoes I have ever owned!Didnt think it was real. it was realI love these shoes and will continue to buy them. I love the cushion.Have taken them out once and feet feel good.
