# Repairing Your Sneakers

A user is required to repair his sneakers periodically to restore its full earning potential. That's the Resilience Attribute of sneakers.

**Resilience Restoration** - While using the WalkN app in Solo or Club mode, a user's sneaker will worn out and would require repair periodically. This is to restore a user's full earning potential. Without repairing, a sneaker would result in less $WALKN/$STEPS output per Energy used. That's why it's important to keep your sneakers' resilience in check to ensure its **Durability**. Also, users need to ensure that their sneakers' never gets to 100% Durability as that will result in an "work-out" penalty, which may lead to sneakers being useless. There are 3 levels of Resilience/Durability for each sneaker and the higher a sneaker's Durability goes, the more expensive it gets to repair it again. 

* At 10/100 Durability, the sneaker's efficiency to earn drops by 10% 
* At 60/100 Durability, the sneaker's efficiency to earn drops by 50%
* At 70/100 Durability, the sneaker's efficiency to earn drops by 95%

So, always make sure to keep restoring a sneaker's resilience to keep it Durable as you use the WalkN app.
