I have very high arches, plantar fasciitis and gets shin splints. I have tried every pair of “high arch” podiatrist recommended tennis shoes. These are the best! Better for me than ASICS Kayano, Brooks Ghost and Glycerin, and Nike Air Pegasus (and others). I’m soooo glad I found these and on sale! The arch is awesome and the tie box is wide.

I love these shoes! I was concerned with the change up, but they are working amazing. They have enough cushion, but it's not too much.

The Ultra Boost 21 has helped me train for 2 marathons with little injury. They are heavy, but worth it for the cushion they provide - also feel great when you put on other shoes because you are used to training in these! The Continental Tread helps me feel safe on wet and snowy grounds too.

Gave the ultra boost 21 a try, loved the older model, but why companies change the fit frustrates me. The size guide said to go a size up - I disagree, my true size is almost too big and it has a larger gappy toe box which is bigger than older models. The heel cushion on one shoe rubs and is malformed after 2 runs - so disappointed. This will become an expensive errand running shoe now.
Rest of the shoe is fantastic... but the top of the shoe is made of such hard plastic they absolutely killed my feet and felt like they were going to break some bones. Thought they would wear in but never did.
I initially liked these shoes but unfortuately after only a few runs, I had to retire them since my calves hurt after wearing these for my long runs. I loved the previous Ultraboosts that I've purchased but not these.
I ran in these a couple of times and felt fast. But in the end, these shoes hurt my calves so now I have a pair of shoes I can't wear :( Be careful of the profile of these shoes and break them in gently if you're not used to wearing the Ultra Boost 21. I loved the Ultra Boost 19s and 20s.
These shoes have never done this to me, but this particular one is hurting my ankle bone. I keep thinking it will go away/get broken in, but so far, they are still not working out.
The toe box elastic is too tight and squishes my toes and causes me a lot of pain so I can’t wear them. If it weren’t for that, I’d love this shoe. The soles of my feet were happy
Love the ultraboosts! So comfy. Perfect for walking. I typically get 1/2 size larger.
