Sizing Guide & Tips

How to Measure Your Foot Length

• If you are unsure of your foot length, measure your feet using our Measurement Guide above.
• Compare with our size chart (provided on each product page).
• Note: Measurement accuracy may vary depending on the drawing. When in doubt, refer to your most frequent shoe size.

Understanding Our Size Guide

Each product page includes its own size guide since different styles may have slightly different fits.

True to Size:

• Sandals
• Open-toe heels (non-thong styles)
• Some mules (with open back)

Size Up:

• Slim loafers
• Pointed-toe mules (especially with back strap)
• If you have wide feet or a higher instep (upper foot is thicker)

Tips for Wide Feet Customers

• For sandals or open-toe styles → choose your usual size.
• For slim loafers or pointy mules → we recommend sizing up to avoid tightness.
• For thong style or strappy styles → we recommend sizing up to avoid tightness.

International Sizing Reference

• Nakedsol sizing is closer to sneaker sizing than international high heels sizing.
• For international luxury heels (e.g., European brands), we usually recommend taking one size up.

Example:

• If you wear EUR 38 in most sneakers, choose Nakedsol 38.
• If you wear EUR 38 in luxury heels, we recommend Nakedsol 39.

Extra Tips

• If your feet are between two sizes, choose the bigger size for comfort.
• If your feet are wide or high instep, size up in pointed style and strappy style.
• If your feet are narrow, stay true to size, or downsize for open toe styles with wide insole.
