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