User opens and closes his magnetic shoelaces (film)
To attach the magnet, first pull the shoelace out of the top 3 holes, then thread it back through the holes of the shoe and the magnet, see youtube.com/watch (last checked June 2020).
When the magnets are separated, the foot can easily be placed in the shoe, then the magnet is closed with a click.
According to the user, the shoelaces work really well. You just separate the magnets. The user notes that the magnets are very strong and they may be difficult for people with poor hand strength to separate.
