Definitions
- the shoelaces of athletic footwear and the drawstrings of athletic clothing are often tied in double knots. Double knots are used because they are generally less likely to open unexpectedly on the field of play or during competition. The durability of double knots, however, often makes them equally more difficult to untie. The difficulty of untying double knots can also be increased by factors such as dirt and moisture. For example, when the shoelaces of athletic footwear or the drawstrings of swim trunks get wet, they tend to swell up. This makes any double knot tied in shoelaces or drawstrings even harder to untie.
