The boots are lightweight and not narrow. For feet 30 cm the size 47 fits well. It’s convenient that the sole is low and the tread is not deep. It's also great that there's no membrane. The boots will dry much faster. There are some molding defects on the soles like bubbles. The instructions indicate a lifespan of only 3 years for polyurethane soles. The insoles need to be replaced because they're not cushioned and the soles are quite stiff. The laces are also too long - 150 cm. 120 cm would be better. There's no indication of where the shoes are made so they're likely made in China. But overall quality is good. These are just first impressions.
