Tires are not the only treads you might need to periodically check. When winter weather strikes, ensure your shoes are up to the task. 
- Avoid high heels and leather soles.
- consider sturdy shoes or boots with rubber soles and sufficient tread.
- Non-slip safety shoes may be required if you work in slippery conditions.
Please be safe out there and help reduce your risk of injury from slipping on snow or ice.
