Shoe Sizing Guide for the Litbuy Spreadsheet

Shoe Sizing Guide for the Litbuy Spreadsheet

Shoes are the most popular category in the Litbuy spreadsheet, and they are also the category with the most sizing problems. The good news is that most sizing issues are completely avoidable if you follow the right process. This guide will walk you through how to measure your foot, how to read the spreadsheet sizing columns, and how to choose the right size for every batch.

Why Shoe Sizing Is Different

Shoe sizing on the Litbuy spreadsheet is not the same as buying shoes from a regular retail store. Different batches are produced by different factories, and each factory uses slightly different lasts — the molds that shape the shoe. This means that a size 9 in one batch might fit like a size 9.5 in another batch, or even a size 8.5 in a third batch.

The spreadsheet addresses this by including sizing notes for each batch. These notes are based on community feedback, and they are the most reliable sizing information you will find. The key is knowing how to read and apply them.

How to Measure Your Foot Correctly

Before you look at the spreadsheet, you need to know your actual foot measurements. Do not rely on your regular shoe size. Grab a ruler or measuring tape and follow these steps.

Step one is to measure your foot length. Place a piece of paper on the floor against a wall. Stand on the paper with your heel touching the wall. Mark the longest point of your foot on the paper. Measure from the wall to the mark. This is your foot length in centimeters or inches.

Step two is to measure your foot width. While standing, wrap the measuring tape around the widest part of your foot, usually across the ball. This is your foot width. Width is especially important for wide-foot buyers because many batches are produced on narrow lasts.

Step three is to measure your insole length. If you have a pair of shoes that fits perfectly, remove the insole and measure it from heel to toe. This is your reference insole length. Most batch-specific size charts in the spreadsheet list insole length, and comparing your reference insole to the chart is the most accurate way to pick a size.

Reading the Spreadsheet Size Chart

The size chart column in the spreadsheet is your primary tool. Most charts list the insole length for each size. Some also list the outsole length, the footbed width, and the internal height. Here is how to read each measurement.

The insole length is the length of the removable insert inside the shoe. It is the best measurement to compare against your foot length. Add 0.5 to 1 centimeter to your foot length to get your target insole length. This extra space accounts for toe movement and sock thickness.

The outsole length is the total length of the shoe bottom. It is less useful than the insole length because it includes the sole thickness and the curvature of the toe box. Use it only as a secondary check.

The footbed width is the width of the interior at the widest point. Compare this to your foot width. If your foot width is more than 2 millimeters wider than the footbed width, the shoe will likely be too tight. Look for a batch with a wider footbed or size up.

Common Sizing Rules by Batch

While every batch is different, there are some common patterns that the community has documented.

Most sneaker batches run half a size small. If you are a true size 9, you will usually need a size 9.5. This is the most consistent sizing rule in the shoe category.

Boots and high-tops often run true to size or slightly large. If you plan to wear thick socks, stick to your regular size. If you plan to wear thin socks, you might be able to size down half a size.

Slides and sandals usually run true to size. Because they are open and adjustable, sizing is more forgiving. However, some slides have narrow footbeds, so check the width measurement if you have wide feet.

Running shoes and trainers often run small. Size up half a size for most batches. Some performance-oriented batches run a full size small.

Width Considerations

Width is the most overlooked factor in shoe sizing. Most batches are produced on standard-width lasts. If you have wide feet, you need to be extra careful.

The first option is to size up by half a size. This adds a small amount of width and length, which can make a standard-width shoe fit a wide foot. The trade-off is slightly extra length in the toe box.

The second option is to look for batches that explicitly note wide-fit compatibility. Some batches are produced on wider lasts, and the community usually notes this in the spreadsheet.

The third option is to choose styles that are naturally forgiving. Slip-ons, adjustable-strap shoes, and soft-material sneakers are more accommodating for wide feet than structured leather shoes or performance runners.

What to Do If Your Size Is Between Sizes

If your foot measurement falls between two sizes, the general rule is to size up. A slightly loose shoe is more comfortable than a slightly tight shoe. You can add an insole to take up extra space in a loose shoe. You cannot create extra space in a tight shoe.

For boots and high-tops, you can also consider sizing down if you are very close to the smaller size. The extra structure and ankle support in these styles help compensate for a slightly snug fit.

Checking QC for Fit Issues

When your QC photos arrive, check the shape of the shoe against your reference. The toe box should look proportional. If it looks too narrow or too short, request an exchange. The insole in the QC photo should be clearly visible. Ask the agent to confirm the insole length if it is not obvious from the photo.

Summary Sizing Checklist

• Measure your foot length and width.
• Measure your best-fitting insole for reference.
• Compare insole length to the spreadsheet size chart.
• Add 0.5 to 1 cm for toe room.
• Check width for wide feet.
• Size up half a size for most sneaker batches.
• Verify the fit in QC photos before shipping.

Final Thoughts

Shoe sizing is the most common source of returns and exchanges in the Litbuy spreadsheet. The good news is that it is almost entirely avoidable. Measure your foot, read the size chart, apply the community sizing notes, and check the QC. If you follow this process, you will get the right fit on the first try.
