Size Guides


Size Measuring using the Keen Size Chart

  1. Whilst standing / wearing a sock - trace the outline of both your feet.
  2. Measure the longest distance. Which is usually from the centre of the heel to the tip of the big toe.
  3. Using the longest measurement (from either the left or right foot) compare to the sizing chart.
