Beautiful boosts, look to be high q / long lasting
Really good looking, they look to be high quality and made to last but time will tell. Only frustration is the move of (nice) boosts in general into Y3 lines with high cost. I'd love some cheaper (nice) boosts for daily use and this used to be an option

Nice colour, quality materials & super comfortable
I’m a size 10/10.5 and always brought ultraboost in 11. There is more room then my last pair but no issues they are super comfy.
