I guess people really want self-tying shoes. Nike is already on their second generation of the HyperAdapt self-tying shoe. Now Puma is joining the field with their own self-tying shoes named “Fi” (Fit Intelligence).
The Puma Fi shoes adapt to the owners feet when they swipe the top of the shoe’s tongue. Inside this elevated tongue is a micrometer that activates a pair of cables for tightening the shoe. If you like your shoes tighter or looser, you can adjust them through a Puma smartphone app or Apple Watch.
