Marcus Johansson #90 (New Jersey Devils) testing the Marsblade Ice Holder.
The ability to keep your balance back and forth over your foot is very specific to ice skating and something that’s important to keep improving to become a better skater. The instability of the Marsblade Roller Frame in general, and especially when using the Advanced wheel setup, helps you to improve this just by skating on the frame. One legged skating drills like in this video takes it to the next level to challenge your balance even more. A progression of this can be to do this drill on a very rough asphalt surface with gravel or similar that will put you of balance even more.
