How to Measure Your Feet

Foot measurement diagram showing where to measure foot length from heel to toe, and calf circumference around the widest part of the calf

1
Place a piece of paper on the floor against a wall.
2
Stand on the paper with your heel against the wall.
3
Mark where your longest toe ends.
4
Measure the distance from the wall to the mark in centimeters.

Measure Both Feet

Feet can vary in size, so measure both and use the larger measurement.

Measure at End of Day

Feet swell during the day, so measure in the evening for the best fit.

Consider Sock Thickness

If you plan to wear thick socks, consider going up half a size.

Brand Size Charts

Brands sized in EU don't all convert to UK sizes the same way. An Aigle EU 41 is a UK 7.5, while a Le Chameau EU 41 is a UK 7. These are each brand's own charts, and they are what the UK sizes on our product pages use.

Brand Specific Sizing Notes

Hunter

Generally true to size in UK sizing. If between sizes, we recommend sizing up. Hunter boots use UK sizes. Check the EU conversion above if ordering by EU size.

Aigle

Aigle boots are sized in EU. They tend to run true to size. Hand-made in France, they offer a slightly roomier fit than Hunter which works well with thicker socks.

Le Chameau

Le Chameau boots are sized in EU and run true to size. Available in multiple calf fittings (38cm, 41cm, 43cm). Measure your calf at the widest point to choose the right fitting.

Muck Boot

Neoprene construction gives a flexible, forgiving fit. Generally true to size. The neoprene stretches to accommodate thicker socks.

The Complete Guide to Wellington Boot Sizing

Getting the right size wellington boots is crucial for comfort, especially if you're wearing them for extended periods. Whether you're gardening, walking the dog, attending festivals, or working outdoors, ill-fitting wellies can quickly turn a pleasant day into an uncomfortable experience.

Why Proper Wellington Boot Sizing Matters

Unlike regular shoes, wellington boots don't have laces or straps to adjust the fit. This makes getting the right size even more important. Boots that are too large can cause blisters and make walking difficult, while boots that are too small can restrict circulation and cause discomfort.

Understanding Wellington Boot Fit

Wellington boots should fit snugly around your foot and ankle while allowing room for thick socks. Your toes should have about 1cm of space at the front, and you should be able to comfortably wiggle them. The boot should grip your heel without slipping when you walk.

Common Wellington Boot Sizing Questions

Do wellington boots run large or small?

This varies by brand. Hunter boots typically run true to size, while Aigle often run slightly small. Always check our brand-specific notes above.

Should I size up for thick socks?

If you plan to wear very thick socks or multiple pairs, consider going up half a size. For regular welly socks, your normal size should be fine.

How do I know if my wellies are too big?

If your heel lifts significantly when walking, or if you need to grip with your toes to keep the boots on, they're too large.
