SIR FUTURE, cushioning and responsiveness at each step!

Sir Future footwear series is the result of research and innovation, values that have always animated our company and that have allowed us to reinterpret the concept of responsive cushioning, developing a product destined to revolutionize the world of safety footwear.
The patented Responder® technology used in the midsole and footbed of the series, represents a real breakthrough in high-performance sole compounds. Thousands of ETPU (expanded thermoplastic polyurethane) beads, with high elasticity and resilience properties, are bound together by a stable, high-resistance compound. This combination creates an outstanding responsive cushioning, extreme lightweights and flexibility over the entire surface of the foot, thus assuring excellent performance even after prolonged and intense use.

Responder® technology has allowed us to create a controlled ultra-low density compound that absorbs shock in the stance phase with a value 90% higher than the limit required by EN ISO 20345, stores energy and releases it back to the foot in the swing phase. This new concept of cushioning helps to save energy much longer than traditional soles, providing the wearer with the best energy return on the market, together with an unprecedented control, stability and ability to adapt.

Responder® midsole spans the entire sole of the foot, providing flexibility and full responsive cushioning. The rubber outsole, with deep longitudinal grooves, accentuates the flexibility of the sole and ensures excellent grip on all types of surfaces. The heel stabilizer prevents foot fatigue and improves foot stability. The combination of all these components allows for a smooth roll-over for an exceptional stride progression.

The “Faster” closure system, fitted on some models in the series, allows adjusting the fit perfectly, making the lacing more even and keeping the tension constant over time. A wide range of uppers made with ultra-modern technologies and high-quality materials complete the ultra-dynamic design of this new footwear series.
