Stride Rite Lace Keepers or shoe lace locks. We all used these with our children years ago, but now they have become a hard to find item. Stride Rite Laces Keepers are a great way to keep your baby's shoes tied. Easy to use: just tie the shoe, slide the Stride Rite Laces Keepers over the lace and screw on the locking lace keeper. Each keeper comes with a bell on top to help you hear your baby's footsteps. These Lace Keepers work best with Infant Laces. Thick laces will not fit into the holder.
