Fizik K1 Donna

Fi'zi:k knows that triathlon shoes play by a different set of rules. Your time can't be wasted on ratcheting buckles, and your feet can't be berated by an ultra-stiff outsole. Basically, triathlon shoes require a system of compromises, yet speed and comfort must still play a vital role. Well, the Fi'zi:k K1 Uomo Shoes have all of these bases covered. With a custom-moldable insole and a stiff, yet compliant, carbon fiber outsole, the K1 checks off all of your boxes for a perfect triathlon shoe.


    We promise to only send you good things.
