The Heel
The Invincible FK3’s heel clip has been significantly updated. It is now thinner and extends further into the midsole, making the back of the shoe more rigid and structured. This change greatly improves heel stability.
The heel of the Invincible 3 is 40mm and includes a reflective pull tab, making it easier to slip the shoes on and off. The design is sleek, with less padding for a more streamlined look while still offering enough support. This combination of comfort and style adds to the overall running experience.

Although not the lightest option, the weight is well-distributed and doesn’t impact performance. This makes the shoe an excellent choice for daily training and longer runs, providing comfort without causing fatigue.
