Because it is a recent purchase, I do not know if the construction quality will prove satisfactory, nor if they are truly waterproof. However, they are much warmer than a comparable Adidas sneaker and my foot sweats with casual walking, so I don't see how they are "breathable". Additionally, their fit is harder and uncomfortable compared to regular Adidas sneakers, while in comparison to Boost, they are a bottomless pit. Finally, the price of €75 for my size may be worth it, but if your size costs €115, it is not worth it.
