It's probably my own fault for not thinking this through before purchasing, but I learned that these laces do not work for higher cut shoes or boots.
My intention was to use these for my higher (just at the ankle) cut boots that I put on after snowboarding.  I wanted to be able to just take off my boarding boots and slip into these in one motion.  Doesn't work.  You have to still release the laces to allow enough room to slip your foot in, then tighten again so it's tight enough to walk in.  Still requires two hands doesn't save any time so I just stayed with my old laces in the end.
