Excellent quality. However, I wear size 45 and Adidas advised me to go for 45+ and they were right, because the foot swells with fatigue and heat and the fit is tight. What I absolutely can't get used to is the extremely soft heel. I almost fell backwards on the staircase because I was carrying a weight and it gave way towards the floor. Good for the foot but you have to be careful. The sole is harder in the middle and moderate at the front for even weight distribution. The extra ReadyBoost sole gives you momentum as you start walking, even more so when running, and it also keeps the foot in place. With light rain, they didn't get wet inside even though I didn't stay outside for long. (Gore-tex model). A bit heavy and bulky, especially for driving. I felt them warm and it was winter, so for spring-summer we forget about them except for rare occasions. Also, the black color attracts heat. The sole is incredibly stable with the Continental rubber, you don't slip even downhill. The height difference of 3cm at the back / 2cm at the front is one of the most balanced, although I would prefer 3/3-flat because I have a problem with the metatarsal. The lace loops at the front and back of the ankle are also nice. Gore-Tex is expensive but I believe the shoe will last for years. Oh, I was also advised not to take them off by stepping on the heel with the other foot even if I have untied the laces so as not to damage the glue of the rear support. That's all...
