For running these are great but, if you put these on your casual walking shoes the laces will put lots of pressure on the top of your foot. Its noticeably uncomfortable. I put these on a pair of sneakers while traveling. During the flights I had them as loose as possible and after 19 hours of travel I have blisters only on the tops of my feet from the constant pressure of the laces.

That said, I used these laces on a pair of Nike's for a race and they were just grand! So my message here is that I highly, HIGHLY advise that you only use these items for active wear only.
