• Sandals and Flip-Flops: These are practical for everyday wear in tropical areas.

• Children's Shoes: If in good condition, shoes for different age groups are particularly needed in some developing countries.

• Good Soles: Soles should not be severely worn and should offer some grip and durability.
• Intact Structure: No large holes or tears, with the upper part and sole securely attached.
• Cleanliness: Shoes should be relatively clean; although perfection isn't required, they should be free from excessive dirt or odor.

Preprocessing Methods

• Cleaning: Clean the shoes before donation to ensure they're presentable. Hand wash or machine wash if the material permits.
• Drying: Make sure shoes are completely dry before packing to prevent mold.
• Inspection: Check each pair thoroughly to ensure they meet the above standards.
• Packaging: Use appropriate boxes or bags for packing to prevent damage during transport.

Shoes Not Suitable for Donation

• High Heels: Often impractical and not durable in the typically hot climates of third-world countries.
• Extremely Worn-out Shoes: Shoes with heavily worn or cracked soles, or significant holes in the uppers.
• Specialty Shoes: Like hiking boots or ski boots, which have limited use in regular donation scenarios.
• Fashion Over Function Shoes: Shoes that are more decorative than functional.
• Out-of-Season Shoes: Such as heavy winter boots, unless the recipient country has a cold season.
