Asymmetrical twins typically have a deeper sidecut on the heel edge rather than the toe edge. For many riders, executing a sharp & rapid turn on the heel side or achieving a deep carve on the heel side can be more challenging than on the toe edge due to the asymmetry in our bodies. This deeper sidecut (asym shape) helps the rider to create a more even heel / toe realignment - great for freestyle, all-mountain/freestyle & switch riding
