The Ground Control Performance Skate Laces are an improved version of the GC Hockey Laces. They upped the wax and threw on some metal lace tips with sickle print.
 
They are a great upgrade from your old laces and able to take on punishment. The wax helps them to stay in place and not loosen up on you while skating. They are 67" (1.70 meters) long, which is perfect for replacing laces on most skates and liners regardless of brand.
