Salomon boot laces

Looked at some Salomon boots with the quick lace system that locks into the plastic thing at the top of the tongue. The guy at R.E.I. said he had tried them and they didn't stay tight. (No, he wasn't trying to sell me a higher priced boot because they didn't have much at end of season). Anybody tried this system and how did it work for you?

Yeah I have a pair as well they usually loosen up a little bit but nothing too drastic, just make sure to wrap the drawstring around your leg and clip it on the other side so it won't come loose. I usually find myself tightening them 2-4 times during a full day of riding; usually once after the first few runs after your foot really compacts in.
I'm switching back to regular lace boots next year if that means anything to you. Unless they are really cheap I would go with another choice (if you have any).

I love how comfortable my Salomons are and have never had an issue with the laces. After a few runs I usually have to tighten them but that's about it. My next pair will probably be Salomon again, but with a BOA system.

I think they work great. I've ridden 3 F series boots to completion. F20, F22, and F24. They fit sooo good and the smaller footprint and bonded liner give superb board feel. I don't have any problem with lace slippage until about day 50 like Rook said. If they fit your feet well you probably won't find any better. IMO they also have the best liner lace out there. that always locks up tight on a single pull and doesn't slip.

^^^^ heater.......  I never take my liners out to dry my boots, and I have use them 2-7 days straight all the time. 

salomon has 2 types of proprietary lacing systems: Powerlace Pro and Speed Power Lace.

Powerlace Pro is their dual zone system and the locks are rock solid.  I've been using this for 2 seasons (almost 50 days) and it has never slipped.  If you lock the zones correctly, you can get an extremely tight fit...even too tight, if you're not careful.  I just bought another pair. 

[If the REI salesman was indeed wearing the F20 (or any other higher-end salomon boot), maybe he is sort of a noob who doesn't realize that once you ride a few runs and everything settles, you're gonna want to re-adjust.  It's not the laces/lock, it's his feet, the liner and shell.]

Speed Power Lace is their low-end, one zone system.  I used the old version several seasons ago and it did slip.
