Carolina Men's Metpro Crazy Hardrock 8" Composite Toe Waterproof Work Boot -Brown- CA7921
Men’s 8” Waterproof Insulated Composite Toe Internal MetGuard These boots are all about protection. An internal polyurethane metguard, combined with a composite safety toe, provides flexible protection and increased comfort, while meeting ASTM standards.

Key Features of the Carolina CA7921 Composite Safety Toe Cap — A non-metallic toe meeting ASTM F2413 for impact (I/75) and compression (C/75), with reduced cold transfer.
