Low stretch cotton blend laces won't slip as you skate. Always have an extra pair handy in case of a show or competition! Size is in inches except Edea which is measured in CM. Please note: 100% cotton laces are not available at this time. We carry both Riedell, and Jackson brands and, because the exact length varies by brand, we will ship the length closest to your order. Risport, Edea, Harlick are also available upon request.
