Simple and versatile, these Blundstone #510 boots are the ultimate wardrobe staple. Comprised of black premium leather uppers, these boots can be paired with any look. Complete with removable footbed and polyurethane outsoles, these boots are also resistant to acid, organic fat and oil, and can withstand microbial attack and hydrolysis. Lightweight and durable, these boots are designed to be comfortable for active feet. Blundstone boots are marked with Australian sizing and differ to UK sizing conventions. The Blundstone Australian size for men is the same as UK men’s sizing. However, the Blundstone Australian size for women converts to one size lower than UK women’s sizing. Therefore a woman who wears a UK size 5 would need to select a Blundstone size 4. Please refer to the Size Conversion Table below. This is a general guideline as foot structure and shape differs from individual to individual.
