How to Measure Your Feet

  1. Measure in the evening when feet are at their largest
  2. Wear the socks you'd normally wear with shoes
  3. Stand on paper and trace around your foot
  4. Measure the longest distance (heel to longest toe)
  5. Measure both feet and use the larger value

Shoe Sizing Tips

  • When between sizes, always choose the larger size
  • Running shoes should have 0.5-1 cm extra room beyond foot length
  • Different brands may vary slightly — always compare by cm
  • Leather shoes may stretch over time, so don't oversize them
