Here is the same review that I had written for the same shoe in all black, since I also bought the red ones:
Summary:
Very stable shoe, now with a wider fit, comfortable (although there are now several softer/more comfortable options), nicely hugs the foot without causing discomfort, nice appearance and seems quite durable. I have walked about 20km and also run a bit and there is no noticeable wear on the sole.
In more detail:
Former owner of Ultraboost 21. I had skipped the 22 because I didn't notice any differences compared to the 21.
Let's talk about the Ultraboost Light (some also call them Ultraboost 23). It's difficult to notice the differences in appearance.
As soon as I tried them on, I noticed them (that's the main purpose of this review).
Firstly, the weight difference is noticeable. Also, they are significantly more stable. I think the fit is also slightly wider. I have wide feet and overpronation. The UB22 simply doesn't work for my feet, just like most neutral shoes.
The UB Light is both comfortable and keeps the foot stable, like a good stability shoe. It also hugs the foot nicely like a sock, without causing any discomfort. Additionally, with thin socks, the foot feels a bit cold at the moment, so I believe they will be great for summer.
I currently own: Adidas Ultraboost 20 & 21, Asics Kayano 28 & 29, New Balance 1080v12, Saucony Endorphin Speed 3, and I have tried many others (Hoka Clifton 8 & 9/Bondi 7/Arahi 6), Asics Nimbus 24/Noosa Tri 14, Brooks Adrenaline GTS 22/Glycerin 20 & 20 GTS/Ghost 15, all New Balance Fuelcell, etc.), so I have a good idea of which shoes are stable and which are not, which are comfortable and soft, etc.
I should also mention the following: I was looking for a sport shoe, as comfortable as possible, to wear daily with cargo pants, chinos, and generally for casual outfits, as I walk several kilometers daily and often need to run due to time constraints.
I was torn between UB Light and Asics Nimbus 25. Nimbus 25 is by far the most comfortable and soft shoe I have worn, and at the same time, it is ALSO stable. An incredible feeling. Unfortunately, it seems too bulky/chunky to me, which is why I chose the UB Light. To each their own.
I bought them for 180€, taking advantage of the current 10% discount running in the company's stores.
