Stretch + Support

Maker and dad, Mike Gonzalez couldn’t untie his son’s frozen laces on a winter day. That prompted him to create a better solution for shoe wearers everywhere.

XTENEX ACCUFIT Laces give your shoes a custom fit. Lace them up as you wish—roomier in some areas, snugger in others—and enjoy the ingenious way they stay put while still
offering stretch or support where you want. Plus your shoes will easily slip on and off, no tying or untying needed.

The funky looking laces have knots every few millimeters. Stretch the laces to thread them, and the knots flatten out and disappear. When you release the tension, they reappear to keep your laces in place.

Perfect for athletic endeavors, ergonomic support, and even for shoes that are too snug with regular laces, this new way of lacing up will happily bring you to your feet.

    Hi Mike. Your laces sound like a dream come true. My size 9 shoes have 6 eyelets, what length do I need? Thanks, Christine

    @Mike Hi Chris, choosing the right size is fairly straight forward, 1st count the total number of eyelets in the shoe - so if you have 6 eyelets on the left side of the shoe you should have a total of 12 eyelets, next take the average width that spans across the tongue of the shoe, (for illustration purposes let's say it's 2 inches) multiply the total number of eyelets by the average width crossing the tongue; in this illustration your length is 24 inches, you always want to choose the exact length or longer when making your selection , never shorter.

    I bought a pair of these at the Wildflower Triathlon a few years back. They are awesome and have outlasted several pairs of shoes. The longevity is an important factor since they are more expensive than some of their competitors. My wife and daughter also use them for racing and training. They are a little difficult to put in and take out, but once you get them set they stay that way.

    Mike, My son plays hockey. Do you think these laces would work in his skates, either roller or ice?

    @Chris Hello Chris, We have sold Accufit laces to hockey players in the past but have never received feedback on how they performed in that particular sport. The laces would certainly work for skates, however, due to their elastic properties, Accufit laces allow for flex of the shoe and may not provide the same ankle stability.

    My husband has Alzheimers and wears "Docker" style shoes Can you make these in dark brown for 2 eyelet shoes. The leather laces always come untied. These sound great!

    Look like a great idea. What is life expectancy for the laces?

    @Louise Hello Louise, Accufit laces have a very long lifespan and are expected to outlast the shoes that you put them in.

    Would these be too big for kids shoes? I don't have them in front of me to count eyelets and estimate the size needed.

    @Lori Hello Lori, Accufit laces are perfect for kids shoes! If it is a younger child, the 20" should work just fine, although it really does depend of the shoe. To be safe, you could use a 30" and if there is excess lace left, a bowtie could be used to prevent the laces from hanging. You could also tie off the lace at the top eyelets and cut the rest off, after the fit has been adjusted just right and is not too tight.

    Due to back problems I cannot tie my shows. Can you use a shoe horn to put the shoes on? I'm also wondering if the tongue of the shoe will get in the way while putting the shoes on? Will the laces be tight enough to wear all day?

  • Mike

    @Ted Hi Ted, a shoe horn can certainly be used to put shoes with Accufit laces on. The tongue may or may not get in the way depending on the material of the shoe (a leather tongue is less likely to interfer than a soft mesh tongue). I would imagine that if the top of shoe was laced loose compared to the rest of the shoe then this would also allow for the foot to slip in without the tongue getting in the way. With Accufit laces, you can adjust your shoes to make them as tight or loose as you find comfortable and will maintain that fit, giving you all day comfort.

    I sure wish you would make these in 54" length. My son has cerebral palsy and just can't seem to tie his own shoes tight enough. Since we have to get shoes that will go around an ankle-foot orthotic, that's the length he needs. With one hand that doesn't work as well as the other, these would be a perfect solution!
