The original.

The look is unmistakably Kizik, but it’s the tech that lit up the world. You step in. The Cage compresses. Then it springs back to hug your heel. Nothing stiff, nothing rigid. Just a flexible plastic lattice that’s strong enough to hold up to every step you take.

Icon, undercover.

You can’t see it, but it’s there. The Internal Cage is a new take on the original: interwoven ribs, this time with more criss-crosses, hidden by the shoe’s upper. You get an undeniable aha moment on the step-in: a soft, responsive bounce-back with stay-in-place comfort.

Cushioned recoil.

We built the heel of this shoe around a firm yet flexible arc that attaches to the sole in a rainbow shape, and it doesn’t like to be held down. Nothing hard, nothing crushable. Just a low-profile, high-rebound crescent that compresses, then pops into place to cushion your heel.

Shockingly simple.

It’s way more than a style piece. The External Flex Arc™ attaches to the sole of the shoe to create our smoothest step-in yet. As you step down, the quick-recovery arc will flex and compress against the back of the midsole, then immediately spring back up to provide a soft and secure fit.

Innovation, integrated.

Not even Kizik has done this before: integrating our hands-free tech with the outsole of a shoe, all in one piece. This bold look begins with a wide-stance outsole that gives you a comfy roll-through stride, rising upward in an arc that wraps around your heel for our most flexible step-in experience yet. The entire piece is made of our own Flex Foam™, which moves with your foot for unbelievable comfort.
