Nice use of stretchy bike tubes to convert a pair of lace-ups to slip-ons! Inner tube laces by jacco1997:
I got tired of my bike’s pedals catching my laces, so I decided to ditch my laces and go for something else. I ended up with using inner tubes to turn them into slip-ons. They stretch out to put your foot in, and stretch back tight. Mine are incredibly comfortable and very convenient.
All you need is a pair of shoes (laced), an inner tube, and scissors.
