# Energy System

Maximum Energy is replenished over a 4-day period in 6-hour intervals (fixed at UTC+0 00:00, 06:00, 12:00, 18:00). Each Energy point equals 1KM of running distance that a user can earn tokens. Owning more shoes will give you more Energy as shown in the below table:

| Sneaker No. | Energy | Daily Repl. |
| ----------- | ------ | ----------- |
| 1           | 4km    | 1km         |
| 2\~3        | 8km    | 2km         |
| 4\~9        | 10km   | 2.5km       |
| 10\~15      | 20km   | 5km         |
| 16\~23      | 32km   | 8km         |
| ≥24         | 40km   | 10km        |

Another way to increase Maximum Energy is to hold higher rarity Sneaker NFTs:

1. R Sneaker (1): +1km Energy
2. SR Sneaker (1): +2km Energy
3. SSR Sneaker (1): +3km Energy
4. UR Sneaker (1): +4km Energy

**EXAMPLE 1:**

1 N Sneaker + 1 R Sneaker = 9km Total Energy (8 Base Energy + 1 Bonus)

**EXAMPLE 2:**

2 R Sneaker + 1 UR Sneaker = 14km Total Energy (8 Base Energy + 6 Bonus)

Listing Sneaker on the Marketplace will result in Energy loss. Transferring Sneaker NFTs from one account to anotehr will result in Sneaker NFT entering into Cooldown period, during which users cannot use this Sneaker.
