Flywire
Flywire helps provide ultra-lightweight support and comfort for your foot. It gets its strength from thin nylon fibers strategically placed on the upper of the shoe to hold the foot in place, helping to reduce slippage during activity. This allows for a massive reduction in weight because material is used only where it’s needed.
