Very good support and at the same time comfortable. I have been using this series for many years without any problems. This time I bought the waterproof ones because I don't run in the summer, so I can't comment on whether they are warm in the summer.

Very good shoe. Very comfortable for walking. When I wear a different shoe and then this one, the difference is noticeable. I wear it every day for over 10 months, for more than 8 hours a day. When the shoe wears out, I will buy exactly the same one

Excellent build quality, giving a more sturdy feel compared to the "regular" Pegasus 36.
Advantages:
+Splashproof
+Non-slip sole for wet surfaces
+Reflective points (such as the white Nike logo)
+Full heel support from below
+Durable fabric in the front and around the toes
+Zoom Air sole for immediate shock absorption and response

Disadvantages:
-It is very warm, so it is almost prohibitive to wear in the summer
-The front part of the sole (with a small Nike logo) tends to detach after stumbling

Overall, I believe that it is worth its price up to 80-90 euros for what it offers.
As for the size, I believe it remains the same in the Pegasus series over the years (my previous Pegasus, the 32 and 27, were also size 45 like the current 36 shield).

EDIT: Regarding the size, for those who will use it for a lot of running, I would recommend going half a size tighter, to avoid having slight gaps in the toes and heel
