"Ava" - Floral Shoelaces.
In most cases you'll need to base the length of laces you need on the number of eyelets on your shoe. (Eyelets are the holes the laces pass through!) 53cm Laces are best for baby shoes or other shoes that only have 2 eyelets per side. 96cm Laces will typically fit shoes with 3-5 eyelets per side. 142cm Laces will typically fit shoes with 6-8 eyelets per side. When in doubt- measure the laces that your shoes came with and use that length as a guide.
