FAQ's | Find out more about R.M.WIlliams Boot Sizing and Unique Characteristics Here:

Do RMW Boots come in half sizes?

YES! Unlike many other brands of footwear. RMW boot half size also affects the length. So a half size will give a little more length as well as fractionally more width. Their quality boots all come in a range of specific widths. Allingtons offer the G and H width fitting, with G being the slightly narrower of the 2. These widths have proven to be the most common sizing widths.    

Do I need to wear in my RMW Boots?

No, they should be good to go as soon as you put them on. Wearing will mould the leather to your foot shape and they will literally fit like a glove. The more you wear them the more comfortable they will get and that is saying something considering they should feel super comfortable from the very start.

How do I look after my new RMW Boots?

A good quality cleaner & conditioner is essential. Making sure the leather stays nourished is critical to enhancing the longevity of your investment.

Is there an R.M.Williams Shirt Size Guide?

Yes, there is. Take a look at the table under the heading "Mens Clothing". This will give a guide to the sizing of the shirt itself. The guide is generic across all clothing styles but is deemed to be accurate. RMW clothing is considered true to size.
