SPLC is a functional shoelace locking system developed with the concept of "making running more enjoyable and comfortable, improving runners' performance."
Quick and easy to put on and take off!
The ergonomic design makes it extremely easy to loosen the laces and take them on and off while running.
It won't loosen or come undone even during intense movements!
They hold your feet firmly in place without loosening or coming loose, even when running on unpaved trails or steep slopes.
Always stay locked.
Even when you get tired after a run, you can release the lock by simply pinching both ends and pulling lightly, without any extra force required.
When you release it, it will automatically lock again.
To lock, simply grasp the center of the locking part and move it toward your ankle. To release, simply pinch both sides and pull toward your toes.
The more you pull the shoelaces, the more the gear digs in.
It has a stronger locking structure.
The locking force is strong enough to withstand a weight of 10 kg, firmly holding the runner's shoes in place. (According to in-house research)
The special string, which is 2mm in diameter, has a core material inside and is resistant to friction and shear.
The material is non-stretchy, so you can stand firm even during intense movements.
It is compatible with various types of shoes and shoe holes (lace holes) such as running shoes, trail running shoes, and leather shoes, as long as they are standard shoes that can accommodate laces with a diameter of 2.5 mm.
(Just like regular shoelaces, if you tighten them too much, you may damage the holes in your shoes.)
With quick and easy operation, strong locking power, and durable laces, the SPLC is suitable for shoes in a variety of situations and can be used by people of all ages, from elementary school children to seniors.
