A heel spur is something most runners fear but the LightSpur designed by Nathan Sport could be something no runner will want to be without after dark. It clips around the heel of a shoe and grips against it while providing an LED light that can help drivers and even cyclists see you at night. The LightSpurs are fully waterproof and powered by a replaceable CR2031 watch battery that should provide more than 100 hours in flashing mode.
These spurs won’t make you run faster but they’ll help ensure you aren’t run down after dark.
