We’re gonna be honest, outside of the end cap falling off, we’ve had little to no problems with the laces on our sneakers. If you’re the kinda guy who wears boots on the regular and happens to put them to good use, you may experience a few more lace-related issues. Castle Brook has you workers covered with the World’s Toughest Boot Laces. Made from 550 lb Army parachute cord with seven strands of military-grade nylon, these laces come with a lifetime warranty you will probably never need. Each pair also comes with high-grade polyolfin nylon aglets (the end caps) and are made in the USA.
