These shoes are not women's. I don't know why the vast majority of stores display them in the women's category. They are the ultraboost J (junior) and they are for kids. They have a less quality sole, harder compared to the women's ultraboost W and they are also 40g heavier per shoe. Possibly their fit is also a bit narrower than the W. I tried one on each foot in the exact same size and the difference in comfort was evident.

These are not the authentic adidas ultra boost, I have the original pair and they have no resemblance in terms of comfort or quality.

Very expensive for nothing! With this money, you can buy from another company and walk and fly! They are simply beautiful and I struggle a lot to put them on because they are very tight

Very good shoes, quality like all ultraboost. I definitely need at least 1 size larger, the 39 1/3 that I always get in my ultraboost is tight like a pump! Also, this particular model fits under the ankle like a sock!
