The adidas Ultra Boost 21 White Solar Yellow adorns the 2015 version in a white, Core Black, pink, and Solar Yellow color patterns. The sneaker's upper is constructed of a prime knit material with a more specific knit construction for added performance and support. It also incorporates pink color scheme, while a recycled Parley Ocean Plastic material shades in its outsole design. White color dominates the upper with accents of Lime Green on part of the vamp section, heel stabilizer and inner lining, while Solar Yellow makes its way on the outsole, and black on the Three Stripe branding on the quarter panels and toe cap. Underfoot, the thick boost midsole incorporates a torsion system, and a rubber outsole graces the shoe. Our experts think the unique feature of this shoe is its torsion system, which consists of Light Energy Push for a more reactive performance. The adidas Ultra Boost 21 White Solar Yellow debuted on February 4th, 2020, and retailed at $180.

Fits small I need a 9 1/2. Do you send me a return label. I have emailed 2x with 1 response saying send back the 9 and buy the 9.5. What is the process (next steps) was my next email with no response.

A good new version of the Boost! Can definitely feel the extra Boost while being a bit stiffer! Not a carbon plate stiffness BUT solid. Use this shoe for everyday miles. Then buy a carbon plate shoe for speed or tempo runs. Much better wear on tread then the old continental rubber. Solid shoe for 50+ miles per week

I've been a lifelong Nike endorser until these came out! Amazing shoe! They take a bit to break in but once they do you'll never go back! I was a huge fan of the Nike free runs and was skeptical that these could even come close... but they did! This has been by far my favorite shoe! I used it for track and xc training.

These shoes are pretty decent. They have plenty of cushioning in the heel for heel strikers. I’m enjoying them for my runs.
I really liked the Ultraboost 20s and bought 2 pairs of the Ultraboost 21 to add in my rotation. I work out 4-5 days a week, doing cardio and weights. And these feel really good on my feet. I am not an avid runner, but as advertised, the additional boost feels more responsive and more cushioned. If you liked the Ultraboost 20s, you'll like the upgrade on the Ultraboost 21s. I am a heavy set guy, I've lost over 60 lbs in the last year, and have put my Ultraboosts through the test...
The fit is almost tight enough not to need any laces. I havent tried the size up. I'm normally a 8.5 on Nike but this is snug fit. The archilles tendon has two plastics to hold the shoe in and its tight if you use any cross training or side movements. Just good for running. Been running on a treadmill and not used outdoor.The top lip of my left shoe flips back and doesnt look all that great when i wear it. If only they moved the adidas label just a bit higher so it wont flip back .
I run from 1 to 1.5 hours daily and have for about 50 years. I buy two pairs of shoes at a time, rotate them daily, and replace them with another pair in about three months. I have worn Adidas exclusively for about 30 years. The Ultra Boost 21 is the most uncomfortable Adidas shoe I have worn. I blame the thick plastic "plates" housing the eyelets through which the shoelaces run. With little effort, the edges of the plates could be filed to a knife's blade sharpness. They are that thick. They are so thick that they inflexible, probably by design. And, other than hold the eyelets for the shoelaces, their only function seems to be to cause the upper parts of my feet to hurt. These shoes are miserable to wear. I am stubborn, so I am going to wear them for three months. ... MoreI run from 1 to 1.5 hours daily and have for about 50 years.

I do not recommend this shoe.
All out red looks exteemely sharp! The extended boost sole looks sharp and provides additional stability. Upper is well made with very little evidence of stich/glue lines. Can wear casually or for running but sole is not flat or firm enough for most gym leg-day exercises. We ordered a full size down as the shoe runs noticably large.
I've had the last three versions of this shoe including an ST version back in the day and this shoe continues to impress. I do a lot of hill work and the new toe plate has been great working through my transitions. I'm normally a size 13 but I always size up for the extra toe box room and this one continued with that trend. The toe plate makes the shoe a tad firmer on the ball of the foot but the performance is still there and it's my new daily work horse. I'm 6'1" and 220lb and this shoe definitely gets the job done.
I'm a fan of ultra boost tech, have had every model and decided to buy this one on sale. When it first arrived I was super excited to try them on. Out the box, my first impression was that it seemed to follow previous models and was made from solid materials, once on foot my feelings changed. Super comfortable, light weight but LONG. Mens size 8 looked more like a 10. The silhouette was more like a clown shoe paired with a huge heel and I just couldn't keep them.
