North Face has created a new system for lacing shoes that relies on a patented technology to properly 'lace' the shoes. The Boa lacing system allows for minute changes in the laces, making sure that each shoe is tailored to fit your foot. The major benefit from this Boa system makes sure that there are no pressure points on your foot. As you're running, you can quickly adjust the pressure, without taking a lot of time out of your run to re-tie your laces.
