I have always worn a sport shoes and now when i saw this video i’m so amazed. Have you ever noticed those extra shoelace holes on your sports and running shoes and did you ever thought for what they are? What is purpose? I have noticed them but i never get some idea for what exactly they are. Usually those extra holes stay unused and that is. Just for that reason , a company that sells LED accessories for runners and cyclists has explained the reason and the brilliant purpose of those extra holes.The extra holes can be used to prevent blisters on your heels and stop your feet from cramming forward into the front of the shoe. So now watch the video and learn exactly what those holes are there and how to use them in the future. We hope that you will love this awesome video. Enjoy!
