Sizing Chart

The most accurate measure is the CMS so use a tape measure and put the heel of your largest foot up against a wall then measure to the tip of your longest toe while standing.

Please ALSO NOTE the cms measurement is designed to allow your arch to drop once tired, and as such is up to 1.5cms shorter than than the actual internal measurement of the footwear.

The INSOLE measurement is the actual measure of the insole which will give you an idea of how much extra space each shoe will have if you follow the recommendations. You may also remove and measure the insole from a comfortable pair of your existing shoes and compare the lengths. It may be that you prefer a neater fit so these measurements will allow you to make up your own mind.

Lems Boulder, Mariner, Nine2five & Chukka

Boulder Mariner & Nine2five are sized differently from Primal2 so be sure to use the right chart and check twice. WE ARE CURRENTLY CHANGING OVER TO UK SIZES WHICH IS WHY THERE IS DUPLICATION OF PRODUCT LISTED.  PLEASE CHECK BOTH LISTINGS OF BOULDER AND NINE2FIVE IF YOUR SIZE IS NOT SHOWING ON ONE OF THEM.

Once you've determined your size, you can double check it by clicking the corresponding Printer Iconand printing out a template.

When printing our copyrighted PDF templates, make sure the "Scale" in the Print Window is set to 100% or the template won't be accurate. If using the Chrome browser, make sure the "Fit to page" checkbox is UNCHECKED.

After you print out the template, also double check the scale by comparing a ruler to the ruler that prints on the template.

Toes should be close to edge, but not hang over. Want our opinion? Send a photo of your foot on the template info@lunasandals.uk 

The biggest issue people have is not having the template accurately printed, so double check twice. ;-)

Simplest way to measure your foot is:  Heel against wall, mark on ground to longest toe, measure in cms, compare to chart below.
