Sizing

Due to the toe shape on this sneaker the fit is very close to the size marked so if you find yourself between sizesit is recommended to go up to the next size.

You can check your closest size by doing the following:

1. Grab a sheet of paper and place it against a wall so the edge of the paper is touching the wall.
2. Now stand on the paper with your heel lightly touching the wall.
3. Mark on the paper where your big toe ends.
4. Measure the distance from the back edge of the paper to the mark on the paper and that will give you your foot length.
5. Now compare your foot length to the chart below which shows the inside length of our shoes. We recommend that the shoe length/size should be 6-10mm longer than your foot length. If you are between sizes always size up.

• Size 37 = 246mm
• Size 38 = 253mm
• Size 39 = 259mm
• Size 40 = 265mm
• Size 41 = 271mm
• Size 42 = 277mm
• Size 43 = 283mm
• Size 44 = 290mm
• Size 45 = 296mm
• Size 46 = 302mm

The above measurements show the internal length of the shoe and your foot should be 6-10mm shorter than this.
