Tips: How long of the shoelace you need?
How many pairs of shoe holes are there on the shoe: n
Distance between two adjacent shoe holes: d
Distance between the hole on the left and the hole on the right: g
Remember the following formula: X = G + 2n * sqr (d ^ 2 + g ^ 2)
This formula only considers the length through the shoe hole, not the length required to tie the bow. The average shoe bow tie needs about 50cm. In other words, X + 50cm is the length of the shoelace you need!
For example, button laces do not need to be bowed, and the length of the laces is 30-40cm less than ordinary laces.
Auihiay 47" shoelaces are suitable for any type of 6~7 pairs of eyelets casual shoes, or boots, even skates, to create your own style.
