FLR F-11 is a premium road sneaker with a seamless upper construction made from a single piece of premium microfiber that conforms to the shape of your foot. The lacing system is based on a single Atop wheel and Velcro strap. Fastening is so simple and secure. A combination of nylon mesh vents, perforated holes and a breathable tongue are used for ventilation. The F-11 features an R250 outsole that enhances performance and power transfer to the pedals.
