4 stars and I will explain. I have had them for 2 or 3 years, I don't remember, possibly three. I wear them every day at work, whether it's winter or summer, in a mine. They are waterproof, comfortable, and the temperature doesn't affect me much. They don't slip much either. Overall, they are worth the money. Of course, after so much use, they show signs of wear and tear. I don't know how long they will last, but they have served their purpose. I should mention that they are made of synthetic leather, so they don't require much care. They are lightweight shoes, which is why I chose them over other brands and models. Now, why 4 stars and not 5? It could have been 4.5, depending on how each person values it and the working conditions. For me, it is a serious issue, and I assume it is a general problem with this company because someone else told me about a similar issue with another model from the same company. The problem, for me, is that over time, the shoe somehow opens up and you lose stability and reliability inside the shoe. To put it simply, if you struggle a little or step on a stone sideways or on an incline, the shoe "turns." It's wide, meaning your foot presses against the sides of the shoe, and if you work on slopes, it can be very tiring because on one hand, you're trying to hold onto the slope, and on the other hand, you're trying to keep your foot in the correct position. I assume this is for people with wide feet, unless it happens to them later on as well, because for me, who doesn't have wide feet, it's not an issue at first. You feel your foot stable inside, and whoever mentions the tightness of the laces, of course I tighten them as much as needed
