Yes, they are! All of the laces featured on our list are very hard-wearing and can stand up to the toughest, wettest and muddiest of conditions without breaking or fraying. It’s a good idea to de-lace your shoes and give your laces a spin through the washing machine now and then to keep them clean and free of dirt and debris. Dirty laces may begin to suffer from damage over time as hardened mud and dirt seep into the material. Excessive dirt and grime can also start to deteriorate the fiber of the laces and cause them to wear out faster than they would if they were kept cleaner.
