Packing: 2 Pair (4 Laces) tennis shoe laces, 24 inches per order (when you select quantity "1", you will receive 2 pairs of shoelaces). Length error range: 2-3 cm (these shoelaces are measured and cut by machine and may have a 2 to 3 cm variation). Material: polyester, with a plastic aglet approximately 2 cm in length. The best way to determine the correct shoelace length for running or sport shoes is to remove the current shoelace from your shoe or boot and measure it from tip to tip. Use this measurement as a guide when selecting your new shoelaces, adjusting the length if your previous laces were too long or too short. These oval athletic shoelaces are suitable for both kids and adults and are compatible with athletic shoes, running shoes, sport shoes, tennis shoes, sneakers, and boots. Available in over 42 colors and multiple lengths, these shoelaces feature a fine texture. Note: slight color variations may occur due to differences in monitor displays.
