I work for a fire department, and don't like to use slip-ons, and laces can be a bother during those late night calls and you need to wake up right away and fiddle with tying boots. This work out great, just set it up like regular laces, feed it through the lock mechanism and boom your done. Now I can use lace type high-top boots, but not worry about taking time to tie in. Just get up, slip em' on, pull the lock to tighten, and I'm done. Nothing really much else I can say about this product, besides that it works. The material feels like good quality. I'll update this after a few good calls, and see how they withstand wear and tear.
