This men’s ski boot is measured in mondo sizing. The easiest way to determine your size is to look at the chart below. Locate your regular shoe size and look down to determine your boot size.
Mondo size can be translated to US sizing fairly easily. Let’s use 27.5 for example. Add the first 2 numbers together and get a 9, then move the .5 behind the 9. Therefore a size 27.5 is relatively a 9.5. It does get a bit more confusing because skiers typically wear a ski boot that is 1 size smaller than their regular shoes. So a person who skis in a 27.5 boot will typically wear a 10 or 10.5 shoe. This simply conversion works almost all the time. It is extremely rare a person will wear the same size ski boot as regular shoe.
