K2 Snowboard Boot Sizes

The Fit

K2 men's snowboard boot sizes are correct if you use Mondo, UK or US sizes but not if you use EU sizes.

K2 women's snowboard boot sizes are correct if you use Mondo or US sizing but not if you use UK or EU sizes. (For example, there should be no difference between men's and women's sizes in the UK)

We recommend:

  • If you have owned K2 boots before, simply order the same size again.
  • Use Mondo or US sizing.
  • If using UK women's sizing, choose a half size smaller than your normal shoe size.
  • If your normal shoe size is UK 6, buy a K2 UK 5.5 = Mondo 25.0
  • Ignore K2's EU sizing or, if you prefer to use EU sizing, we have added a final "EU Absolute" column showing the correct conversion from Mondopoint.

    How to Measure Your Foot Size

    Snowboard boots are sized using the Mondopoint system which is very simple, making it nice and easy to choose the correct boot size. The Mondopoint size is the length of the inside of the boot liner, measured in cm.

    To work out your size, the best way is to look it up on a pair of snowboard boots which fit you well but, if this is your first pair, measure the length of the insole on your best fitting pair of trainers. Remove the insole and measure, using a steal measuring tape, from the extreme tip of the toe to the extreme tip of the heel.

    The measurement will always be exact to the nearest 0.5cm. You will never get 30.2 or 28.8; it will always be 30.0 exactly. This is your mondo shoe or boot size.
