So Ill Approach Shoes & Footwear Size Chart, Guide & Fit Advice

So Ill men's shoe sizes are correct if you refer to Mondo, US or UK sizing.

Etnies women's US shoe size are a half size too small.

Etnies 'translation' to EU sizes is only correct in some instances so is unreliable

We therefore recommend:

    ●  If you have owned So Ill footwear before, simply order the same size again.

    ●  Use Mondo, US or UK sizing.

    ●  If using US women's sizing, choose a half size bigger than your normal shoe size.

         If your normal shoe size is US 6, buy a So Ill US 6.5

    ●  Ignore Etnies' EU sizing.

         If you prefer to use EU sizing we have added an "EU Absolute" column showing the correct conversion from Mondopoint.  EU shoe sizes increase in 3.333mm increments - which is why, when presented to a single decimal point, they should always end with .0, .3 or .7 and never with .5.

How to Measure Your Mondo Size

The Mondopoint size of a shoe is the length of the shoe's insole measured in cm. To work out your size, the best way is to look it up on a pair shoes which fit you well or to measure the length of the insole on your best fitting pair of shoes. 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. Checkout this video to have Adam explain it all in plain English.  He is using a snowboard boot but the same principle applies to all footwear.
