All shoe sizes on product pages reflect US shoe sizing.

How To Select Your Size

Size Up

We recommend ordering Mizuno running shoes 1/2 size to one size larger than normal dress shoes.

(If ordering from our WAVEKNIT collection, Wave Rider 25 WAVEKNIT, or the Wave Inspire 18 WAVEKNIT we recommend going up a FURTHER ½ size from your usual running shoe size.)

Select Width

Men's footwear:

D is the standard width and 2E is a wide fit

Women's footwear:

B is the standard width and D is a wide fit.

Unisex Sizing

For a women’s fit when ordering "unisex" shoes, please order 1.5 sizes smaller than your usual US Women’s size. E.g. if you usually fit a US Women’s 9, please order a Unisex US 7.5.

Get Fit

We always recommend heading to your local running store to be measured up, however if you can’t make it into store as an alternative, we recommend measuring your feet at home by following these easy steps:

What you will need:

  • Pen/Pencil
  • Paper
  • Ruler/measuring tape
    1. Place the piece of paper under your foot and stand with your heel against a wall
    2. Trace your foot as closely as possible
      (Be sure to trace both feet, as one foot is often longer than the other)
    3. With the tracing measure a straight line from the back of the heel to the longest toe
      (This will give you the length of your foot in centimetres)
    4. Add 1-1.5cm to this measurement to give you the most accurate length for your shoes
    5. Take this total measurement in cm and using our international sizing chart match it to your US size.
