Kevlar laces will not rip or shred as regular laces will over time. What differentiates these laces is the Kevlar fibre that they are made of, which is high-tensile strength. Kevlar is known for its toughness and superiority over other fibres. Kevlar laces are often used for work boots, outdoor rough wear boots, firefighter boots and hiking boots. They can withstand extreme strength as well as heat. Proper maintenance should not be a problem, but it will help ensure that your Kevlar laces remain strong and clean for years to come.
Straighten out the Kevlar laces when new. They should be even in length, about 54 to 72 inches each. Insert laces into boots or shoes as you normally would add laces to shoes.
Keep the Kevlar laces or shoes with the laces in temperatures between -10 degrees C and 260 degrees Celsius to avoid damage.
Wash Kevlar laces in a washing machine using warm water and detergent. This will help remove stains and will not harm the Kevlar fibres. Kevlar laces can be washed over and over again as well as dried in a dryer. Pin them together using a safety pin for easier removal from the washer and dryer.
Use oxygen bleach such as OxiClean to remove tough stains from Kevlar laces. This will not harm the laces; however, chlorine bleach will harm them and cause them to break.
Wear the Kevlar laces normally after each wash, regardless of the terrain or surroundings. Kevlar laces are durable and made to resist heat and damage. The only thing you need to worry about is keeping them clean and tied tightly.
Always tie the laces tightly or even use double knots. The fibres of the Kevlar lace make them more slippery than regular laces, which causes them to untie easily.
