New Balance Calibre Zip Sided 4E Wide Safety Boot MIDCLBRE4E

The New Balance Industrial Calibre 4E Safety Boot combines the comfort of a performance-inspired work boot with dependable protection for demanding job sites. Designed with an extra-wide 4E fit, it provides additional room for workers who prefer a broader fit.

The water-resistant leather upper is built for durability, while the composite safety toe delivers impact protection without the weight of traditional steel. An anti-perforation midsole provides added underfoot protection, and the slip-resistant outsole is designed to provide reliable traction across workplace surfaces.

For convenient everyday wear, the Calibre features a YKK side zip alongside heel and tongue pull tabs, making it easier to put on and remove. The NB PU comfort insert and supportive heel counter help provide cushioning and stability during long working hours.
