XTENEX (indeXed-TENsioning-nEXus)

This worldwide patented technology produces a sustainable customized tension fit between shoe eyelets. Patented Xtenex technology sets incrementally spaced knots along a strong rubber core. When stretched the knots reduce for adjustment at an eyelet, then systematically reemerge to lock-in an ergonomic fit. The strong rubber core keeps the knots emerged, this allows the footwear to be securely fastened while converting lace-up footwear into convenient slip-ons. This effective lacing system is perfect for runners, walkers, handicapped persons, children of all ages, athletes... anyone whose wants comfort, support and a customizable fit.

What are Xtenex laces? 

XTENEX is a worldwide patented elastic shoelace technology that produces adjustable tensioning between each shoe eyelet.

This technology addresses the source of footwear related pain and discomfort: lace migration.

Lace migration is the gradual movement of the shoe lace toward the forward bend of a shoe, which causes two main problems:

1.     Binding; a tightening and restricting pressure at the top of the shoe. This can lead to foot fatigue, pain, numbness and restriction of natural foot swelling.

2.     It loosens the fit around the footwear's metatarsal area, which causes increased slipping and reduction of forward foot stabilization. This can produce heat friction, which often leads to painful blisters. The unique design of the Xtenex lacing system solves the problem of lace migration.

Xtenex laces have an elastic core and a series of knots along the entire length of the lace at consistent length intervals. Stretch the lace and the knots disappear, allowing you to thread the lace through the eyelets. Release the tension and the knots reappear. More knots between eyelets lessens the tension; fewer knots between eyelets increases tension. This technology enhances footwear fit, comfort and performance through its many advantages.


Advantages of Xtenex laces :

  • Expansion:  Expand during natural foot swelling and eliminate foot compression.


  • Do not slip:  The knots maintain the original fit by restricting involuntary lace movement through the eyelets (lace migration) keeping the foot stable in the foot bed and increased comfort.


  • No plastic pieces are needed.


  • Eliminates "dual-compression impact":  Impact #1 = shoe sole hits ground. Impact #2 = foot hits foot bed/sole of shoe.


  • Converts laced shoe into a perfect fitting slip-on:  Never Tie Your Shoelaces Again!


  • Asymmetrical lacing:  The shoe upper can be molded to the natural, nonsymmetric, form of the foot by independently adjusting the tension between each set of eyelets. The unique ability to have different tension zones along the entire lacing system results in a custom fit every time.


  • Enhanced lateral stabilization:  This is achieved by increasing the tension along the left or right side of a shoe upper. This helps to stabilize and support the foot within the foot bed while enhancing footwear and foot care technologies such as orthotics, arch supports and insole technologies.


Medical testimonials:

Michael A. Goldman, D.P.M. Alpine Foot & Ankle Clinic
"Id like to thank you for introducing my patients and me to your product. Ive not been enthusiastic, in the past, about elastic shoe laces; however, with your imaginative modification to the laces, I have become an endorser. The Xtenex laces do not slip, keeping the heel in the proper shoe location and not causing the toes to encroach into the end of the toe box. These laces also do not damage the Dorsal Medial Cutaneous Nerves of the instep. My patients with severe arthritis, post surgery laminectomy or spinal fusions find these laces quite convenient. Again, thank you from my patients and me; keep up the good work."

"I teach doctors about feet, gait, and orthotics that treat athletes around the world at every level. I look for products that give an advantage of time or function that I can rely on. The Xtenex shoe lace is one of those products. It combines the flexibility of Stretch, Strength, Stability and Security to a shoe that you only have to tie once. The collapsible knot technology is great for Triathletes or anyone who does not want to keep tying shoe laces but wants their shoe to just slip on."
