This tool helps users estimate how long their insoles will last based on their weight, daily usage, and insole type

How It Works:

1. User enters weight, daily usage, activity level, and insole type.
2. Click “Calculate Lifespan”, and the tool estimates how many months the insoles will last.
3. If a replacement is needed, the “Buy Replacement Insoles” button appears 
4. Clicking the button redirects to Amazon, where users can purchase a replacement insole.
