The toughest laces on the planet

Neon green Castle Brook Paralaces

Guaranteed to outlive whatever boots/shoes/Herculean sandals they're looped through, Castle Brook's Paralaces are the self-proclaimed "toughest laces in the world" thanks to their seven interwoven strands of military-grade paracord, sealed with incredibly durable nylon aglets (the tips on laces that prevent unraveling or fraying). And to back said claim up, they've been extensively tested under the most brutal conditions -- burned, frozen and, uh, "beaten".
