My young daughter plays basketball and doesn't always notice or can't stop in the middle of a game to tie her laces.  These were easy to install and we're hoping they'll work well. If buying for a child I would go with what other reviewers said and buy one size up so there is enough leftover lace for little fingers to pull on - it creates a bit of excess lace but not enough to touch the ground and this can be tucked under the laces
