Forma boots run mostly to everyday US sizing, but there are some points you need to consider as you may need to size up. With every brand there is always some sizing variation, especially with US sizing. Euro sizing is the most consistent sizing standard worldwide, so if you know your EU size, that is always the best reference.

Most Forma boots are a 'unisex' fitment, the larger sizes are a mens fitment and morph down to a womens fitment in the smaller sizes. 

Motorcycle boots are designed to be firmly fitted to hold the boots in place and give maximum feel of the controls. They are more rigid for protection with internal and external plastic components. This protective design will make the boots feel smaller or tighter than your regular shoes or sneakers. Regular shoes will flex and accommodate wide or large volume feet, but in most cases you will need to size up as motorcycle boots have limited flexibility. When sizing up, don't be concerned the boots will be too long as there is only a ¼ inch difference in length between most sizes. Also consider that motorcycle boots are designed longer in the toe box to give extra frontal protection, and that can give the impression that the boots are narrow when in fact you only need the next size. And with waterproof boots, the WP membrane reduces the foot chamber volume giving the boots a slightly tighter fitment. 

There is not one official Footwear Size Standard that all manufacturers follow, so do not assume your size! Measuring your feet is the most successful way to establish the correct size first time around.

*The best sizing method is to measure your feet by placing your heel against the wall and measure out to the end of your big toe, then add 1 inch to give you the 'inside measurement'. (smaller sizes only need to add 3/4 inch) 

The 'inside measurements' are listed below so you can more accurately establish your size. Of course we cannot guarantee that you receive the correct size because every foot shape is different, but in most cases the size is correct first time around. If required, we will work fast to correct any sizing issues. Fitment is 4-Dimensional (length, width, volume and instep height) and unfortunately it's only possible to accurately measure your foot's length.

Please factor in all these points when selecting your size.


95% of our customers receive the correct size first time, but if you find that you need to exchange, breathe easy we will work quickly to exchange sizes.
