# Energy and Durability

#### Energy

Activities in Pro Mode consume energy. Energy is affected by the number of shoe you are holding and grades of shoe NFTs in your account.

#### Durability

Durability falls while using energy.

According to the table below, the efficiency of point acquisition falls as the durability falls below a certain level. Therefore, it would be necessary to repair shoes at the right time so that the durablilty would be maintained above certain levels.
