Derby Laces Waxed Laces are braided from a blend of high tenacity yarns that are exceptionally soft and resistant to moisture.  Their high tensile strength makes them suitable for roller derby and other rough skating, while their large and constantly expanding variety of attractive colors and designs makes them perfect for accessorizing any skate or outfit. These laces are treated with a performance wax that feels awesome and helps the laces stay tied, tight, and where you want them while skating. The plastic tips are molded right out of the lace itself so there is no plastic or metal bits to peel off and any damage that does occur can be repaired easily with a small flame.
