Inspired and influenced by Korua Shapes park-oriented ambassadors, the Otto is a freestyle-focused carving board with a twin-like shape and a slightly softer flex and torsion than our other classic line boards. These qualities make it a super playful ride on snow and in the air, ideal for carving in and out of side-hits, hitting park features, and creative cruising all over the hill. It’s a perfect fit for riders who want to focus on their turns without sacrificing freestyle performance.

The Otto features our FLOAT CAMBER, which curves into a rocker shape in the nose. This profile provides excellent float in deep powder while maintaining speed throughout the turn. The camber under-foot offers extra pop for ultimate air-time and stability for carving on-piste, while the early rise in the nose allows for an easy initiation of turns.

This chart shows the range in what each size can handle. It is never our intention to categorise riders and their preferences. Our philosophy of snowboarding is to try new shapes, lengths, widths, and to keep an open mind for alternative riding experiences; however, we do have some limits to consider so that your board will work as it was designed to.

Your weight plays a major role in how the board will flex, and your shoe size will affect toe and heel drag when turning. The below size chart is for reference only, as our recommendations may vary depending on your stance and riding ability.
