Choosing a slingback size starts with your foot measurement. A ruler and a few minutes can help you compare your foot length with the measurements listed on a supplier size chart. This is especially useful when a product lists supplier sizes rather than standard US size conversions.
Measure both feet, then use the longer measurement when checking the chart. The steps below explain how to measure heel to toe and match that measurement to a listed Supplier Size.
What You Need to Measure Your Foot
You only need a few basic items. Measure on a hard, level surface, and keep your weight on your foot while you mark it. This helps capture the length you need when standing.
Paper, pencil and a ruler
Gather a piece of paper large enough for your foot, a pencil, and a ruler or tape measure that shows inches or centimeters. Place the paper on the floor against a wall so it does not slide. If someone can help, they can mark your foot while you stand.
How to Measure Your Foot from Heel to Toe
Measure each foot separately. Feet can differ slightly in length, so checking both gives you a more useful number for comparing with a chart.
Mark the heel and the tip of your longest toe
Place one foot on the paper with your heel lightly against the wall. Stand naturally and keep your toes relaxed. Mark the paper at the back of your heel, then mark the tip of your longest toe. Your longest toe may not be your big toe.
Repeat the process for your other foot. Measure the distance between the two marks for each foot, and keep the larger measurement. Use the same measuring method for both feet so the results are comparable.
Measure in inches or centimeters
Use a ruler to measure in a straight line from the heel mark to the toe mark. Record the result in inches or centimeters. If you record both, write down the numbers shown by the ruler rather than estimating a conversion.
For example, a foot length of 24.0 cm corresponds to 9.45 inches in the chart below. Compare measurements in the same unit whenever possible, and keep the recorded value handy while viewing the product page.
How to Match Your Measurement to a Supplier Size Chart
Once you have your foot length, look for the closest listed measurement in the product chart. Check the specific product page before ordering, because available Supplier Sizes and listed measurements can differ between products.
Match the foot length to the listed Supplier Size
Find your measured length in the chart and read across to the Supplier Size in the same row. The measurements below show the listed foot length in both centimeters and inches.
| Supplier Size | Foot Length (Centimeters) | Foot Length (Inches) |
|---|---|---|
| 35 | 22.5 cm | 8.86 in |
| 36 | 23.0 cm | 9.06 in |
| 37 | 23.5 cm | 9.25 in |
| 38 | 24.0 cm | 9.45 in |
| 39 | 24.5 cm | 9.65 in |
| 40 | 25.0 cm | 9.84 in |
| 41 | 25.5 cm | 10.04 in |
Why supplier labels are not standard US size conversions
A Supplier Size is the label used in the product’s supplier chart. The foot-length measurements above do not provide a US size conversion. Compare your measured foot length directly with the chart instead of choosing based on a familiar US shoe-size number.
How to find your size:
1. Place your foot on a piece of paper and mark the tip of your longest toe and the back of your heel.
2. Measure the distance in inches or centimeters.
3. Match your measurement with our chart below.
Please note: Our sizes are based strictly on exact foot length measurements from our supplier, not standard US size conversions.
What to Check Before Choosing a Slingback Size
Before ordering, confirm that the product page shows the size you plan to select and that its foot-length chart matches the information you used. Check the listed product options, photos, and any product-specific details. The chart is a reference for comparing measurements; it does not guarantee that a style will fit every foot shape.
Available sizes and product options
Review the available Supplier Sizes on the product page, then compare them with your measured foot length. Product options can vary, so use the chart and selections shown for that specific pair. Check that the size is available for the color or design you want before proceeding.
If your measurement falls between two rows, the chart does not provide a fit recommendation, so avoid treating either row as a guaranteed fit. Use the exact measurements provided for the product and contact the store before ordering if the listed information is unclear.
Measuring in inches or centimeters gives you a direct way to compare your foot length with the supplier’s listed information. For an example, see the Women’s Clear Slingback Heels with Sparkling Bow product page and review its available options and size chart.
