Derby Laces are treated with performance wax, so they stay tied, tight, and where you want them while skating. These laces are braided from a blend of high quality, high tenacity fibers. They are exceptionally soft, have high tensile strength, and are resistant to abrasion and moisture. Derby Laces feature a tri-fold tip molded out of the lace material itself. There are no plastic or metal bits to peel off or break. The lace tip is easy to lace and extremely durable. Simple damage can be repaired by flaming the tip.
