Size and Width Guide

Last updated: September 22, 2026

If your feet have gotten wider or your toes need more room than they used to, you already know that going up a size does not always solve the problem. A longer shoe with the same narrow shape can still leave your toes cramped, and worse, it can leave your heel loose and slipping with every step. This guide walks through both length and width, since getting either one wrong is the most common reason a shoe gets returned.

Does this shoe run true to size

Yes. Our sizing follows standard EU and US foot length measurements, shown in the chart below in both centimeters and inches. We recommend measuring your actual foot length rather than relying on the size printed inside your current shoes, since sizing can vary between brands, especially with footwear made in different countries.

EU to US size conversion

Use your longest foot measurement. Measurements below are foot length, not shoe length. Each row lists foot length in cm and inch.

Do you offer wide widths

Yes. Each style is available in four widths: Narrow (B), Standard (D), Wide (2E), and X-Wide (4E). This replaces an earlier approach of building extra room into a single standard fit. If your foot is wider than average, or you have struggled to find shoes that fit through the forefoot without the heel slipping, choosing the correct width is a better solution than sizing up in length.

These width options are everyday fit choices for different foot shapes. They are not a medical claim or treatment.

How to choose your width

Width is measured straight across the widest part of your forefoot, not your heel or your ankle. Once you know your foot length from the size chart above, match that same size row to the width measurements below to find where your forefoot falls. Every cell shows inch / cm.

If your measurement falls between two widths, choose based on your preferred fit, snugger or roomier, or email us before ordering and we can help you decide.

How to measure your forefoot width

• Stand with your full weight on a sheet of paper, the same way you would for measuring foot length
• Wrap a tape measure or a piece of string straight across the widest part of your forefoot, usually just behind your toes
• Measure the distance in inches or centimeters and match it against the width chart above for your size
• Measure both feet, since one is often slightly wider than the other, and choose based on the wider foot

What if I have a higher instep

Slip-on styles rely on some stretch and give across the top of the foot to get on and off easily, which also helps accommodate a slightly higher instep. If your instep is unusually high on top of needing a wider fit, choosing Wide or X-Wide along with your correct length is the better approach, rather than sizing up in length alone.

Will the heel slip in a slip-on shoe

This is the biggest risk with any slip-on, and it is worth taking seriously. A shoe that is too long for your actual foot will often let your heel lift and slide with each step, even if the front of the shoe feels comfortable. Our slip-on styles are built with a secured heel cup designed to hold your heel in place at your true measured size. That structure works best when the shoe is sized to your actual foot length and width, not sized up in length to compensate for a narrow fit.

Should I size up

Generally, no, not in length. Sizing up used to be the only way to get extra room, but it adds length rather than width, which is exactly what causes heel slip. Now that Wide and X-Wide options are available, the better fix for a tight forefoot is choosing a wider width at your true length, not a longer size. If your true foot length measurement falls between two sizes, sizing up slightly in length is still reasonable.

What socks should I wear to measure

Measure your foot in whatever socks you plan to wear most often with these shoes, or barefoot if you usually go sockless. If you plan to wear thick socks in colder weather, measure with those on, since it can add a small but real difference to the fit.

If the size or width is not right

If you follow this guide and the fit still is not right once your order arrives, our Refund Policy covers returns within 30 days. If you are unsure before ordering, email your foot length and forefoot width measurements (in inch or cm) to help@roampaths.com and we will help you choose.

Measurements are a sizing guide. Fit can vary slightly by shoe style and individual foot shape.
