How to Choose the Length of Your Shoe Laces? Choosing the correct shoe lace length depends mainly on the number of eyelet pairs and the spacing between them. As a general guide: 4–5 eyelet pairs: 27–36 inches 5–6 eyelet pairs: 36–45 inches 6–7 eyelet pairs: 45–54 inches 7–8 eyelet pairs: 54–63 inches 8+ eyelet pairs: 63 inches or longer For sneakers and sports shoes, 45–54 inch laces are commonly suitable, while boots and high-top footwear generally require longer laces. Tip: If replacing an existing lace, measure the old lace from end to end. This is usually the easiest way to select the right size.
