human: I am planning a walk around the EU outer boarder. Tell me how long would it take and how much walking shoes should I buy beforehand?

assistant: The EU's outer border is not a continuous or easily walkable path, and it includes maritime borders, mountainous terrain, and areas with restricted access. Therefore, calculating the exact distance or time required to walk around the entire border is challenging. Additionally, the EU's borders might change due to political developments or membership changes, so it's essential to stay updated on the current situation.

However, if you still wish to undertake this journey, you can estimate the distance and time required for your walk. The total land border length of the EU is approximately 13,000 kilometers (8,078 miles), excluding the maritime borders. Assuming you walk an average of 25 kilometers (15.5 miles) per day, it would take you around 520 days to complete the journey, without accounting for rest days, border restrictions, or other unforeseen factors.

As for walking shoes, their lifespan depends on the quality, materials, and usage. Generally, a good pair of walking shoes can last between 500-800 kilometers (310-500 miles) before the cushioning and support begin to degrade. For a 13,000-kilometer journey, you would need at least 16-26 pairs of shoes to ensure proper footwear support throughout your walk. It's essential to choose shoes that offer a balance between comfort, durability, and support.

Keep in mind that this is a rough estimate, and your actual requirements may vary based on your walking speed, terrain, and personal preferences. Moreover, considering the complexity of the journey, it's crucial to plan carefully, ensuring you have the necessary permits, visas, and accommodations along the way.

human: Do you have any suggestions for proactive measures to maintain the health of my feet?

assistant: Yes, it's essential to take proactive measures to maintain the health of your feet during a long-distance walk like the one you're planning. Here are some suggestions:

1. Choose comfortable and supportive shoes: Invest in high-quality walking shoes that fit well, provide adequate support, and have good cushioning. It's essential to break in new shoes gradually before starting your journey to avoid blisters and discomfort.

2. Use moisture-wicking socks: Choose socks made of moisture-wicking materials that can help prevent blisters and keep your feet dry.

3. Stretch and massage your feet: Regularly stretch your feet and massage them to improve circulation and prevent stiffness and soreness.

4. Practice good hygiene: Wash your feet daily and keep them dry to prevent fungal infections, such as athlete's foot.

5. Take breaks: Take regular breaks to rest and elevate your feet, especially after walking for extended periods. This can help reduce swelling and fatigue.

6. Consider using orthotics: If you have foot problems or a history of foot injuries, consider using custom orthotics or inserts to provide additional support and cushioning.

By following these proactive measures, you can reduce the risk of foot injuries and ensure your feet remain healthy and comfortable throughout your journey.
