Getting the size right matters more with barefoot and natural-movement shoes than with a normal sneaker, because the whole point of the category is a wide, foot-shaped fit and a true zero (or near-zero) heel-to-toe drop. This Sole Mechanics sizing guide walks through how the retailer’s in-person and virtual fitting services work, how sizing differs brand to brand, and how to measure your own feet before you order, so you don’t end up guessing.

Why Barefoot Shoe Sizing Is Different

Conventional sneakers are built on a tapered last that narrows toward the toes, so brands can get away with sizing purely by length. Natural-movement brands use a foot-shaped last that’s as wide at the front as your actual foot, which means fit depends on width and toe splay as much as length. Order your normal size in a barefoot shoe without checking the brand’s own chart and you can end up with something that’s either sloppy at the heel or too tight across the forefoot.

In-Person Fitting at the Hampton Street Store

For anyone local to Victoria, Sole Mechanics’ physical store on Hampton Street offers hands-on fitting: staff measure both feet (most people have one slightly larger than the other), assess your current gait and any foot-health concerns, and bring out multiple brands so you can compare a true zero-drop shoe like a Vivobarefoot against a cushioned foot-shaped option like an Altra side by side. This is the fastest way to get sizing right on the first try, especially if you’ve never worn a natural-movement shoe before.

Virtual Fitting Consultations

If you’re ordering online from elsewhere in Australia or New Zealand, Sole Mechanics also runs virtual sizing consultations. You’ll typically be asked for a couple of measurements and photos of your foot, plus details on what you’re currently wearing and why you’re switching. The team then recommends a specific size and, where relevant, a specific brand based on your foot shape rather than a generic size chart.

Brand-by-Brand Sizing Notes

How to Measure Your Foot at Home

Stand on a sheet of paper against a wall, weight evenly on both feet, and mark the tip of your longest toe and the back of your heel. Measure the distance in centimetres, then repeat for the other foot since most people have a size difference between the two. Also trace around the widest part of your forefoot; natural-movement brands care about this measurement more than mainstream shoe charts do, since a narrow last will still feel wrong even if the length is correct.

Common Sizing Mistakes to Avoid

The most frequent mistake is assuming your usual sneaker size carries over directly, especially between brands within the barefoot category itself. The second is skipping the width check and only measuring length. The third is ordering a size down “to be safe” in a true zero-drop shoe like the Vivobarefoot Gobi III, when in most cases true-to-length is correct and sizing down just cramps the toe splay the shoe is designed to allow.

Our Verdict

Rating: 4.5/5

A retailer is only as good as the support behind the sale, and this is where Sole Mechanics earns its reputation: genuine in-person and virtual fitting expertise across a wide range of natural-movement brands, rather than a generic size chart copied from the manufacturer. If you’re new to barefoot shoes, using the fitting service before you order is worth more than any single review of a specific model. You can start a fitting request or browse the current range directly through Sole Mechanics.

Frequently Asked Questions

Do I need to visit the store in person to get sized correctly?

No. In-person fitting at the Hampton Street store is the most thorough option, but the virtual fitting consultation covers most online AU/NZ customers using measurements and photos instead.

Does Sole Mechanics sizing carry across all the brands it stocks?

No, sizing is brand-specific. Vivobarefoot, Altra, Xero and Inov-8 all fit differently from each other, which is exactly why the fitting service exists rather than a single universal size chart.

What should I measure before requesting a virtual fitting?

Length and width for both feet, since most people have some size difference between them, plus a note on what you currently wear and why you’re switching to a natural-movement shoe. You can get started through Sole Mechanics.
