Extra Sneaker Holes
If you wear sneakers, you must have taken note of the extra holes that come at the top of shoes. No, this is not a design error! When your shoes run a little bigger than your feet, it is common to get blisters. Aside from that, it must make for an uncomfortable fit. This problem can be addressed if you slip the shoelaces into the opposite hole! You can create a loop this way and have a tighter lock. If you wanted to hear what this was called, you should keep in mind that it is called the “lace lock” or the “heel lock”.
Holes In Padlocks
We all use a padlock for one reason or another! Have you ever noticed that there is normally a hole or two located at the bottom? The holes allow water to come out if they ever get in. Some locks are kept outdoors, so they must be ready to face the elements. If it jams, just pour oil or WD-40 in there.
