In case of doubt about the size:
1- Place your feet flat on two sheets of A4 paper.
2- Draw the two lines with a pencil, as close as possible.
3- Measure the longest length in cm (possibly the width in case of a strong foot or oedema). Indicate the values in the "comment" box further on in the order.
When you receive your shoes open.
Cradle your heel in the heel cup of the Finn Comfort sole - at the edge of the sole. Your arch should be in a natural and perfect position. Adjust your straps and stand. Your longest toe should come to the edge of the seam, or even 3 to 5 mm into the pick-up.
For closed shoes, you should have 8 to 10 mm to spare.
At Finn, if you are a size 38 in closed shoes, you are a size 37 in open heel shoes (mules, sandals,...).
