Now, we're happy to introduce version 2. If you're looking for a boot with multiple applications, the Shift2 incorporates our IFC – Instant Frame Change - concept. With the sole t-nut hardware removed, you can depress the 2 buttons on the base of the soul, release the slider, and from that point – the soul, frame and wheels – from the boot. Within seconds, you can snap on a fresh setup, all without having to access any of the UFS hardware, and you’ll be on your way. With the addition of t-nuts on the inner/negative part of the sole, and new Reign liner, we've created a more stable, comfortable, and reliable skate. Out of the box, the Shift2 is designed to hold up to the serious demands of modern day street skating.
