The lifespan of Irish Setter work boots can vary depending on factors such as usage, maintenance, and the specific model of the boots. On average, well-maintained Irish Setter boots can last anywhere from one to three years, but this is a general estimate and may differ based on individual circumstances. Regular cleaning, conditioning, and proper storage can contribute significantly to prolonging the lifespan of the boots. Additionally, the frequency and intensity of use, as well as the type of work environment they are exposed to, will impact their durability.
