Xtenex at trrail.com: elastic laces that never come undone

Xtenex makes elastic laces with knots that hold your shoe firmly but give when your foot swells during running. You never have to tie them again, and your laces won't come undone on the go.

The laces

You replace the X300 Original Lace in a few minutes. After that you step into your shoe without tying. Ideal for triathlon, ultras where your feet swell, and anyone fed up with loose laces.

Frequently asked questions

Will my shoes still fit snugly?
Yes, the knots keep the lace under tension. You can adjust the tension by lacing it tighter or looser.
