nike flywire
due to the vectran fibers, shoes containing nike flywire weigh as little as 93 grams, "approximately the weight of a snickers bar with a bite missing." there is little excess weight because the upper is very thin, and the vectran fibers are only added where support is needed. shoe weight can be reduced up to 50% through the use of flywire. track spikes (running shoes with spikes added for traction) containing flywire are now lighter than michael johnson's famous golden shoes of the 1996 summer olympics in atlanta, georgia. these spikes are so light that athletes claim they are like "a second skin" or "spikes coming out of their feet." this is a goal that bill bowerman tried to achieve as co-founder of nike and a spike designer.
