New Balance uses Nanofront® nanofiber for replacement insoles

August 2nd, 2012 / By: / Industry News

Teijin Fibers Limited, the core company of the Teijin Group’s polyester fibers business, has announced that it is supplying its high-strength polyester nanofiber Nanofront® for use in replacement insoles for running shoes made by New Balance. The insoles will be marketed by New Balance Japan and sold in its directly owned shops in Tokyo and Osaka, as well as other sports retail stores nationwide beginning this month.

Nanofront is a high-strength polyester fiber with a thickness of just 700 nanometers, or 7,500 times smaller than the cross section of human hair. Nano-sized bumps on the surface raise frictional force and produce a surface area dozens of times greater than that of regular fiber, resulting in highly superior slip resistance, to help prevent a wearer’s foot from sliding inside a shoe. Nanofront also boasts high moisture absorbency and diffusion for added comfort. It’s also used in shoelaces and socks made by New Balance Japan.

Teijin Fibers started commercial production of Nanofront in 2008 and has been developing applications in areas such as innerwear, sportswear and industrial materials.
