Grip Tie Products was born on the soccer field, and expanded to the world - untie-resistant flexible shoe laces that are easy to use and give a competitive edge to all: young or old, sporty or fashionable. They operate just like a normal lace, replace your old laces and tie as usual - but they have a tiny amount of stretch that make them more comfortable and supportive, and the regular knot you tie will resist untying until you pull on it directly. No need for clips or special knots.
They have responded to COVID by developing first responder shoe laces that are similar to their regular sport laces, but are also fireproof. They also have a mask "quick tie" product that makes masks easier for seniors and disabled. More information here.
