Measure your foot for DayLite Hiker

Sizing for a boot is different than a sandal. And you probably have boots / shoes of different sizes that fit you correctly. Also, the DayLite Hiker runs small so you may need to choose a size larger than your usual size.

So, to reduce the chance of getting an incorrect size, we HIGHLY recommend you follow these instructions.


Since the foot is three-dimensional, any two-dimensional measuring tool, such as a ruler or Brannock device, can only approximate your true shoe size. Manufacturers model their shoes on different foot shapes, so sizing may vary accordingly.

Our sizing recommendations are based on customer feedback, however we cannot 100% guarantee a proper fit.

Step 1 - Measure your foot

Place a piece of paper against a wall (if you have VERY large feet, use a piece of newspaper.

Place your foot on the paper, with your heel against the wall.

Make a mark on the paper at the furthest point away from the wall… this will either be just in front of your big toe or second toe.

Take a ruler and measure from the edge of the paper to the mark you made.

Here’s a video showing the process...

Step 2 - Check your measurement against the sizing chart


- For the most reliable fit, we recommend you use the foot length sizing info in the table below.

- The maximum recommended foot length is the insole length less 8mm.

- If you have an existing pair of similar shoes that fit comfortably, you can also compare the insole sizes.

- If you already have Xero Shoes sandals, you MIGHT need one size larger in the DayLite Hiker.

- If you think you’re "between sizes" we recommend you go up to the larger size.
