SPLC Speed ​​Racing System

A functional shoelace lock system developed based on the concept of "making running more fun, comfortable, and improving runners' performance."

First time SPLC^®When attaching shoes to shoes, be sure to wear shoes and cut and adjust the length of the laces so that they can be put on and taken off smoothly. The length of the laces is 140 cm, so if they are too long, you may feel a little uncomfortable while running, and if the laces are too short, they will feel tight when you take them off. Please adjust the length according to your shoe type and preference. If you set it to a longer length, passing the end part under the string will prevent it from flapping.

1) Always keep locked.
Even when you get tired from running, just pinch both ends and pull lightly to release the lock, no need for extra force.
When you release your hand, it will lock again automatically.

Simply hold the middle of the lock part and move it to the ankle side to lock it easily. To release, simply pinch both sides and pull toward the toes.

② The more you pull the shoelaces, the more the gears dig into the shoes.
It has a structure that locks more strongly.
With a locking force that can withstand a weight of 10 kg, it firmly holds runner's shoes. (*In-house research)

③ The special string with a diameter of 2 mm has a core material inside and is resistant to friction and shearing.
The material does not stretch or contract, so it can be stepped on even during intense movements.

Standard shoes with a lace diameter of 2.5 mm are compatible with various types of shoes such as running shoes, trail shoes, leather shoes, and various shoe holes (lace holes).

(As with regular shoelaces, if you tighten them too tightly, you may damage the holes in your shoes.)
