1What 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, we recommend you follow the sizing chart and instruction below:
If your foot length varies more than 1/6in. it will be difficult to get a precise fit for both feet.
If your second toe is more than 1/6 in. longer than your big toe it may be difficult to get a precise fit.

PLEASE NOTE: FOOT LENGTH IS MEASURED IN INCHES, NOT SHOE SIZE.
