Forma boots generally follow standard everyday U.S. sizing, but there are some important points to consider as most riders will need to size up.
All boot brands have some size variation, especially in U.S. sizing, because there is no official size specification that manufacturers follow. Euro sizing, however, is the most consistent standard worldwide, so if you know your EU size, that will always give you the best reference point.
Forma boots use a unisex last, with larger sizes being the perfect mens fitment and smaller sizes morphing down into a women’s fitment.
Motorcycle boots are more rigid due to internal and external protective components. This construction design can make the boots feel smaller or tighter even when the internal dimensions match your regular shoe size.
Where sneakers and soft shoes flex to adapt to wide or large volume feet, motorcycle boots will not have the same flexibility and many riders will need to size up with their boots. Addtionally it's best to have a generous fit, to allow for feet swell on long rides. Don’t be concerned about the extra length when sizing up: most size increases only add around ¼ inch.
Also note that motorcycle boots have a longer, reinforced toe box for toe impact clearance, which can give the impression of narrowness even though the foot chamber is correct. Additionally, waterproof models have a WP membrane that slightly reduces foot volume, giving them a smaller feel as well.
In most cases your motorcycle boots will need to be one size larger than your sneakers.
Measuring your feet is the most accurate way to establish the correct size on the first attempt.
The best method:
Place your heel against a wall and measure to the tip of your big toe.
Then add 1 inch to determine your ideal “inside boot” measurement.
(For sizes under Men’s 7 / EU 41, add ¾ inch.)
We list the internal boot measurements below so you can select confidently, and in most cases riders get the right size on the first order. If you do need to swap out sizes, we’ll take care of it quickly for you.
Please consider all these points when selecting your size.
