New technologies with expanded capabilities set the Caliber work boot apart from previous New Balance work footwear offerings. This 6-inch nubuck leather lace-up boot, in dark brown, has a convenient YKK side zipper. Debris Free and H2O Resist construction helps keep debris out from the shoe and the nubuck leather repels water. Toe Protect bumpers supply additional exterior abrasion protection while a composite toe cap within the shoe meets ASTM F2413 standards for impact and compression. These shoes also supply underfoot protection. Kevlar, when combined with an Acteva foam midsole gives you comfort and puncture-resisting protection underfoot. These shoes meet ASTM F2413 standards for electrical hazard and puncture resistance. An AT Tread outsole allows you to traverse between flat and varied terrain and meets or exceeds ASTM F3445 slip standards for work footwear.
