RM Williams boots are built for durability and an authentic Australian feel, and selecting the right size is essential for comfort and long wear. This guide explains how RM Williams sizing compares to standard measurements, which fit and width options suit different foot shapes, and how to match your existing footwear to an RM Williams equivalent. You will find practical fit checks, heel‑to‑boot fit guidance, and ordering tips so you can choose confidently the first time.
How RM Williams Boots Sizing Works
RM Williams typically uses a traditional UK-style sizing system with half sizes and multiple width fittings, which can differ from modern athletic shoe scales. If you know your usual UK boot size, start there and confirm with the brand’s size chart for the specific model, because lasts vary across lines. Use a Brannock device or trace your foot on paper to capture length and compare it to RM Williams internal measurements rather than relying on the labeled size alone.
Understanding Fit and Last Shape
RM Williams boots are constructed on classic European lasts that often produce a slightly narrower profile than casual sneakers. If you have a medium or wide forefoot, consider trying a wide fitting or adding a thin in‑sole to improve volume distribution. Check for sufficient toe room in a seated position while ensuring the heel remains stable when you stand and walk, which reduces blister risk and hot spots.
Width Indicators to Watch For
Width fittings are important for comfort, especially if your feet swell during the day or you wear thick socks. Look for width markers such as D (standard), EE (wide), or EEE (extra wide) in product descriptions, and verify that the ball of your foot aligns with the widest part of the boot without pressure. Adjusting lacing and using thin or padded socks can further customize fit without changing the size number.

Practical Size Conversion and Reference Points
Use approximate conversions as a starting point, then confirm with the specific model’s size chart. If you shop between regions, align your foot length in millimeters with RM Williams size guides rather than relying only on labeled UK, US, or EUR numbers. Measuring your foot at home and comparing it to the brand’s millimeter ranges is the most reliable method to avoid returns.
Men’s and Women’s Quick Reference (Approximate)
- Men: UK size 8 ≈ US 8.5, EUR 42
- Women: UK size 5 ≈ US 7, EUR 38
- Half sizes are available; select the larger size if between whole sizes
- Check the model-specific size chart, as variations occur across boots and seasonal lines
How to Measure Your Foot for RM Williams Boots
For best results, measure at the end of the day when feet are at their largest, and wear the type of socks you intend to use with the boots. Stand on a flat surface with your heel against a wall and mark the longest point of your foot. Compare that length to RM Williams millimeter measurements on the size chart, because this is more accurate than aligning shoe length alone.
Step‑by‑Step Measuring Guide
- Place a blank sheet of paper against a wall and stand on it with your heel touching the wall.
- Hold a ruler or measuring tape flat against your foot at the longest point, typically the back of the heel to the tip of the big toe.
- Record the length in millimeters and compare it to the RM Williams size chart for the specific model.
- If your measurement falls between sizes, consider half sizes and evaluate the intended use and sock thickness.
Trying Boots In‑Store and What to Check
When possible, try on RM Williams boots with your planned socks and the orthotics you intend to use. Walk in different directions on a test surface to evaluate heel slip, forefoot width, and overall comfort. Pay attention to pressure points on the instep, ball of the foot, and ankle, since small issues can become painful over long wear.
Key Fit Checks While Trying On
- Heel: It should lift only slightly during walking and not cause friction.
- Instep: Lacing should be snug without cutting off circulation.
- Toe Box: Allow a small thumb’s width of space when seated, so toes aren’t cramped.
- Width: The widest part of your foot should align with the boot’s widest section without pinching.
Online Ordering Tips and Returns
When buying RM Williams boots online, verify the size chart for that model and compare your foot measurements directly. Note any comments about fit tendencies, such as runs small or true to size, and consider customer reviews from people with similar foot shapes. If returns are available, use them to confirm comfort, especially for extended wear or uneven terrain.
Order‑Ready Checklist
- Measure both feet and use the larger measurement
- Consult the model‑specific size chart in millimeters
- Decide on width fitting if you need extra volume
- Plan for intended socks when evaluating size
- Check return policies in case adjustments are needed
Common Fit Questions and Troubleshooting
Some people find RM Williams boots run slightly narrow across the forefoot. If this matches your experience, try a wide fitting or a half size up, particularly if you plan to wear thicker socks. Heel slip can occur with new boots; consider using heel‑grips or checking lacing technique before sizing up, which can create excess forward slide on the foot.
When to Size Up or Down
- Size up if you add thick socks or experience toe crowding when seated
- Size down only if the shoe is clearly too large and can be adjusted with insoles or lacing
- Prioritize comfort in the instep and heel over trying to force a smaller size
RM Williams boots are designed to last many seasons when sized correctly, so investing time in fit checks and accurate measurements reduces the chance of exchanges and returns. Use the brand’s official size chart, confirm width needs, and test fit in person when possible to ensure your boots support every step.
