The principle of reflective shoelace is that the middle gray-black layer contains high refractive index glass microbeads, which reflect the incident light back to the light source according to the original path to form a retro-reflective phenomenon. Because it focuses almost all the light back at a very small angle, its brightness is much higher than that of ordinary objects. The quality of shoelace reflection depends on the quality of glass beads on the surface. The better the bead quality, the smoother the surface and the better the reflection.Therefore, when tying shoelaces, you may feel that the material is too hard and slippery, which makes it difficult to tie them firmly. However, you can tie your shoelaces easily if you soften them a few times..
