The idea behind ReflecToes is that our eyes are wired to detect motion and instantly recognize "biological motion" (familiar, human motion). So the best place to put reflective when running or cycling? Your legs!
There is an older man in my neighborhood that is super dedicated and I see him out jogging all the time...but he doesn't wear any reflective. So I don't see him until he is uncomfortably close and deep in my headlights.
Drivers need to see him from a long distance since more and more, drivers are glancing back and forth from their phone to the road. He wears florescent orange sometimes, but that doesn't work at night (needs UV light from the sun). If he had reflective on his legs the smallest amount of light from oncoming headlights would reflect back to the drivers eye *as motion* from over 1,000 yards away, giving even the distracted driver time to notice between phone glances.
ReflecToes a technical sports sock that that has more and brighter reflective than any out there and is wash durable by using a proprietary design and adhesive. As soon as we get our first batch of ReflecToes my neighborhood jogging grandpa is getting a pair!
