Midfoot, forefoot, or rearfoot strikers – all runners who want to step on the gas have one thing in common: they touch the ground farther at the front of the sole. This is exactly where we placed a new version of our unique U-TECHTM technology, Double U. Inspired by the natural motion you sink into the twofold U-shaped construction. U-TECHTM surrounds your foot, centers forces and thus provides you with support and physiological assurance. Like a trampoline, it catapults you forward into the next step. A newly designed last ensures a performance fit that surrounds your foot like a second skin. Our Speed MotionBridge, a fiberglass-nylon plate which was incorporated into the midsole, provides added stability, reduced weight, and a dynamic and explosive push-off. The U-TECH Solo is through and through pure innovation that you will hopefully love as much as we do. A true whirlwind!
