Product description
Freestyle performance, redefined
The Union Ultra offers a riding experience that is like no other. Each component is crafted to respond to your movements, return energy, and absorb vibrations, ensuring complete control and comfort. From explosive take-offs to smooth landings, the Ultra remains reactive, responsive, and plush. This latest version features upgraded technology, including the three-piece S11 Asym Baseplate, the S15 Ultra Duraflex Highback, and the new Hybrid 1.0 Ankle Strap. With the Tool-less 3.0 strap adjustment system, setup has never been easier.
Highback
The S15 Ultra Duraflex ST Highback is made for freestyle riding. It provides lateral flex while ensuring a swift response when necessary.
Baseplate
The asymmetrical S11 Asym Baseplate allows for natural board flex and feel. The heelcup is securely locked in place with Astro Washers. The Molecular Bushing System maximizes damping and rebound on impact. A TPE outsole prevents snow build-up, and the Non-Stick footbed stops ice from forming underfoot.
Straps
The new Hybrid 1.0 Ankle Strap combines a responsive exoframe shell with a slim, cushioned interior for high comfort and control. The TS 5.0 Toe Strap moulds seamlessly to your boots for a secure, pressure-free fit. Tool-less 3.0 strap adjustment makes customization fast and simple.
