108 inch (274 cm) skate lace with strong metallic fibers, high performance braid, and hardened plastic tips suitable for roller derby and other high performance skating.

PERFORMANCE METALLICS
SPARK by Derby Laces create a natural friction when tightened to help them stay tied, tight, and where you want them while skating.

DURABLE FIBERS
SPARK by Derby Laces are braided laces made out of metallic coated durable fibers. They have a unique texture that allows them to tighten and loosen easily.

HARDENED TIPS
SPARK by Derby Laces feature either a hardened plastic tip or a custom metal tip. Both are extremely durable.
