Thanks ST.  I think my problem is that I was tying off the two ends together and that left too much lace hanging.  Your way ought to work just fine and I'll give it a try.  By the way, you can get those cord locks at MEC for 30 cents each although I guess we all have a ton of them lying around from disposed bags that developed holes.

I tried this method a few years back before someone stole my idea ;D
I found the spring in a gear bag wasn't strong enough to hold a shoe like a laced knot. Not saying some wouldn't work, but the ones I had failed under pressure.

The ones I linked you too, have a very strong spring, and a two-stage lock. When you press them slowly, they open up allowing movement. A quick press, and they click-lock into place, locking them very securely.

I'm sure that's why there so much more expensive than the standard ones. If anyone can get old gear one's to work satisfactorily, then your ahead of the game.

In any case the concept works really well and is worth a look, if your tired of laces coming untied at the worst moments :'(

Thanks for tech info. I'll try and remember to post my links like Jimbo did, so everyone can see them.
