Find My Shoe Size

To find your size, place a piece of paper on a flat surface and place it directly up against a wall. Stand on the paper and ensure you have a 1mm gap between your heel and the wall. Plant your foot firmly on the ground and slowly roll your weight forward and onto the forefoot. For the most effective longest toe measurement, your heel should lift off the ground slight. Look down and take the measurement from the wall edge of the paper to your longest toe. Record the length. With your foot still in place, mark the widest points of the inner and outer edges of your feet. Measure the width across the widest part of your foot and record the number in millimeters. Repeat this step for both feet.

Once the measurements have been taken, use the Foot Length Range on the size chart to find your size. The Last Length measurements shown on the chart are the exact length of the last that we use to build the shoes. This correlates to the precise internal measurement of the shoe.

Following selection of your size in EU or USA, move downward to select the most appropriate width. We recommend adding 1mm to find the most appropriate width. For example, you are looking at a Vaypor S and have determined your best shoe size is 45 and your feet measure 105mm (left) and 107mm (right) wide, with an additional 1mm added, you would still fit within the Standard Range. If your feet measure wide than 109/110mm (size 45/10.5) you should consider Wide fit.
