Besides having gone through tightness tests carried out at Cimac, this innovative solution has been tested by a large group of women – of different age, weight and height – who have been wearing 100 mm heel court décolleté shoes without steel shank for more than eight months, without highlighting any critical issues.
Instead, they shared enthusiastic opinions regarding the following:
1. shoes are lighter and, consequently, make you less tired, especially considering how many steps you take during the day, and thus reduce the impact on muscles. In fact, a NPU Green insole made without steel shank weighs 30% less than one made of traditional materials and with shank;
2. the shoes don’t set metal detectors off, thus allowing a smooth walk-through. This can be very interesting not only for those who travel a lot by plane, but especially for those who, for work, must go daily to courts, bureaus and all those places where metal detectors are required;
3. the shoes convey a feeling of stability. Walking, especially in high heels, stresses the back of the shoe (the trunk), most of all transversally. An insole made of NPU Green ensures a transversal resistance superior to any other material usually used, even without steel shank, considering that the latter contributes much more to the insole longitudinal resistance than to the transversal one.
