What Size is Right for You:

Foot shapes and sizes vary greatly. FiveFingers do provide some fit adjustment, but may not fit every foot type. To achieve the best fitting results for the particular style you are interested in, FiveFingers recommends you follow the sizing chart and instructions below:

1. Stand with your heels flush against a flat vertical wall.

2. Slide a ruler under each foot and measure the distance from the wall to the tip of the longest toe.

3. Take the longer of the two foot measurements.

4. If the foot length varies more than 1/6 inch, it will be difficult to get a precise fit for both feet.

5. If you second toe is more than 1/6 inch longer than your big toe, it may be difficult to get a precise fit.
