the boots are really light, not heavy at all! the material feels a little bit too thin but that makes the boots really comfortable. my size is a EU38 and I bought a EU39, and I'm glad that I did that, I totally recommend that you go a size up or else it will be too tight.
Love them. Order 1 size bigger tho. I’m usually EU38 but I ordered EU39 and they fit perfectly! They’re very very comfortable too, love the lining inside it is very soft and warm :)
