Men's Size Guide

We offer a variety of cuts and fits to accommodate a diverse customer base, and the exact sizing will vary slightly between styles.

As a US brand our shoes and boots are lasted and sized in US sizes. In recent months we have implemented a companywide revision of our size conversion to bring consistency to our multi-branded business. This may mean the labelling on the boots and/or box may differ from your order. However, your order will have been cross referenced with the US size in our conversion chart to ensure your boots should fit as expected.

If you are making a repeat order note the US size you have as the US size is consistent.

FAQs

HOW ARE OUR WELLIES SIZED?

SIZE v FIT? Everyone’s feet are individual, and we know correctly fitting boots are important. Remember SIZE and FIT are different and any size guide can only be indicative. Fit is affected by the style, last and manufacturing technique used. In most instances our EU sizing runs true but using our measuring guide will help direct you to the right choice. The correct fit allows for room in the toe box (your feet get longer flatter and wider when under load) and no heel slip. Too big and the heel slip risks damage to you and the boot. Too small and you risk black and bruised toes as they hit the end of the boot. For those who are a half size, order the next size up.

THE HEELS ON MY BOOTS ARE SLIPPING. WHAT CAN I DO?

While we have invested heavily in our shape and sizing, our boots often do not have a lacing system to customise the fit. If your boots slip at the heel, placing heel grips inside will help secure your foot and minimise internal wear.

I HAVE WIDER CALVES, WHICH WELLY WILL SUIT ME?

Neoprene has several features that lend it to making boots – waterproof, self-insulating, breathable, shock-absorbing, flexible, and exceptionally comfortable. However, its stretch-ability also means we can accommodate a range of calf shapes and sizes than regular boots. We also have a collection of mid-height wellington boots that offer all the style and practical benefits of our wider calf wellies, but with a lower cut that many find more comfortable.

HOW ARE UNISEX STYLES SIZED?

Unisex styles are built on men's last. For ladies with wider feet, we would recommend our unisex styles as they tend to be roomier than women's styles.
