The eyelet hook on boots are extremely dangerous if you don't lace up your boots all the way. I know for a fact that not everyone laces up their boots all the way every time. I have had some severe falls when the laces of my boots catch the empty eyelet hook of my other boot. The last time it happened I swore it would not happen again so I designed this eyelet cover that prevents the lace from going into the empty eyelet hook.
Use a pair of pliers to squeeze the plug into place.
This will only work with TPU.
