I bought the shoe in size 42 and realized that there is a big difference in sizes compared to Nike.
Since I wear size 42 in Nike, I wanted size 41 in Adidas.
As a result, the shoe is a bit big for me, but it is very nice, comfortable, and relaxing

I found them for only €30, but I didn't find them satisfactory. They seem hard and somewhat tight on the sides, even though I got a half size bigger than normal. Obviously, I didn't get them for sports, but for everyday use, with a little walking, etc.
They are nice in color and design, as they appear in the photos, but in the end, Adidas is satisfactory only in appearance (compared to Nike of similar price).
Also, I should mention that I read in another comment that it hits the right foot, and unfortunately, I have the same issue.

Update 5/9/2023
They have loosened slightly after months of use. Although there is enough room in the front, as I got a bigger size, they still remain tight on the sides. Also, they are suitable for a simple walk with moderate walking. After a while, they start to tire a bit.

Comfortable, nice appearance. The major drawback is that they "crack" and develop lines within a few days - and I only wear them at work (in an office) and I don't put any strain on them at all.

I mainly wear them for walking.
They are lightweight and in my opinion, perfectly soft.
I got size 44.5, but I probably wanted size 44 as they are a bit wide.
They don't have that annoying back hit in the first few days... thankfully.
The color is a true deep blue, the sole could be a bit thicker (you can feel it when changing gears on the motorcycle...)

Guys, I have had them for 4 months, wearing them almost every day and they haven't even got a scratch.. very lightweight shoe, hugs the foot nicely, you can get them for 35 euros, just blindly

They are worth every last euro. I had them for about a year and a half and wore them daily for many hours until the sole melted from walking.

They do not have the quality they should. You have the feeling that they are made of cheap plastic. They have an issue with the fit. After days of use, this did not change.
