スタンディングデスクに使ってます。製品に問題はないのですが、寒くなって靴下を履くと足を乗せるザラザラの部分で靴下が脱げてしまうか、靴下が擦り減ってしまいますね。なんとかしたいです。良い方法あれば共有してほしいです。【追記】カインズのタイルカーペット（298円、サイズ40x40㎝）がボードの直径にピッタリで、カーペットのゴム側を上にすると靴下でも大丈夫でした。生地側だと滑ってダメ。自己責任でお願いします。

This is for beginners; not very challenging. Its well made from what I can see but the ball below the board is a bit broad and so the equilibrium its quite easy to keep. There are similar boards that are more challenging.

Yes I paid the extra $1 for the wheel one. I’ve sprained my ankles twice the past year, using this to strengthen my ankles. Roll it around, left to right front to back and can try 1 foot in the center with support later on. Closer to the center is more difficult. Works muscles all through the body, particularly the ankles and lower body. Focus on having good posture while balancing.

I've gotten so good at balancing!
