Very lightweight and comfortable boots! I wear size 45 in regular shoes, not athletic ones, and size 45 is just fine with the lining. Without the lining, they are a bit big but within acceptable limits. So the size is calculated with the lining

Truly unbelievably lightweight, comfortable fit, warm without making your feet sweat, and with a soft sole that doesn't feel like a rain boot at all. The best.

Very good, although quite expensive for rain boots. They are extremely lightweight and do not tire even in muddy fields. The downside is that they are very susceptible to cutting or puncturing due to their soft material.

Very good, lightweight, comfortable, with good grip and without hurting the foot.
As for the lining, it is very good and fits inside the boot, while the insole has external material to prevent slipping.
As for the size, I wear Nike 45 and I got them in 45. I wore them with athletic socks and their lining. It was perfect.
So comfortable that they don't even feel like boots.

Incredibly lightweight, comfortable, and warm, it doesn't remind you at all of the classic rain boots.
I don't have an opinion on durability, I received them today.
Get the size you wear in athletic shoes, etc.

Comfortable, lightweight, and warm with nice lining. I wear a size 45 to 46 in athletic shoes. I got the size 45 and it fits me perfectly.

Very good. My size is 40-41. I bought size 41 and it is a little big but it didn't bother me during the long walks I took in the heavy snowfall in Attica. Definitely comfortable and warm. Recommended.

Very good, comfortable, convenient, warm, and they don't easily make your feet sweat. No comparison to the others I have worn

Very comfortable, lightweight and durable. Very convenient that the interior can be removed for washing. Worth checking them out.
