  • 2 years later and these are still my favorite shoes!
Wow I bought these Dec 2022 and these babies have been THRU it. They’ve been washed in the washer, pressure washed & handwashed/soaked many times and they’ve held up great! The weight of them are a little denser but I love how comfortable they are! The white color has held up great but after 2 years the soles are starting to wear off the white paint. I am going to buy them again this time in black and white again because they held up so good with washing. I believe they are a bit expensive HOWEVER they are worth it. I could probably go another year with them but I’ll donate them to less fortunate so they can still get more great use out of them. ... show more

  • Adidas Ultraboost 21 running shoes- BEST ULTRABOOSTS YET!
Color: Black/Black/Black Size: 8
Ok, I’ve been wearing Adidas Ultraboosts for a few years now. Every season I buy at least 2-3 pair bc last year I had trouble finding more before the 21’s came out and kind of panicked (it brought flashbacks of when my fave Salomon running shoes were discontinued… I still get twitchy about that). I realllllllly like the 21’s (3 pair so far; all black, pink and light blue, and I’m going to buy another couple pairs of black bc I mostly wear black, AND bc most of the colors this season are really light with a white sole - I run and walk five dogs outside, and I’m just really active inc many treadmill miles every day, and the pink pair was trashed after just two wears, unfortunately). The shoe feels and fits more like a really snug sock, and it’s super comfortable. What I really like about them are the soles. They are much wider and feel a lot more sure footed when running. Still super lightweight, but something about the new sole and snugger sock-like fit makes them SO MUCH BETTER. I highly recommend. Thanks, Adidas, for making such a kickass, reasonably priced shoe. You have a customer for life if you never stop making Ultraboosts. ... show more

  • Significant price difference
Color: Black/Black/Grey Size: 10
Amazon offered these running shoes at a significant discount. They are no different than the shoes bought from the Addidas website. Due to my size, foot shape and arch, these are the only shoes that I have used for several years.
