Flextra

 

Flextra-elements are strategically incorporated into the outsole in the forefoot area. These elements are designed depending on gender and weight to provide the necessary forefoot stability.

 

Flextra is a system of individually configured flex grooves. It guarantees every runner ideal forefoot flexibility independent of weight and gender.

 

Our product developers differentiate by using three different flex groove designs. The less outsole material is being utilized the more flexible the shoe becomes. The smaller men’s sizes (US 7-10,5) are moderately flexible while the bigger men’s sizes (US 11-15) are less flexible. All the women’s shoes are genderspecifically more flexible.
