Xtenex Custom Shoe Laces

The ultimate shoe laces for runners… in cute colors? Yes, there’s even a science to the perfect shoe lace, and Xtenex has mastered it with their patented elastic lace technology that produces “adjustable tensioning between shoe eyelets.” We were surprised too, but here it is: the solution to “lace migration.” You may be surprised to hear people talk like this about shoe laces, but Xtenex’s are used by Olympians who know a thing or two about making sure they have addressed every conceivable issue with their gear.
