Tips for sizing your foot correctly:

Please note that Ocun has specifically designed their shoe sizes to remain consistent across the board. This also means that if you usually aggressively downsize in other brands, that won't be helpful here.

  1. Using a tape measure for best accuracy, measure from heel to toe and compare to the MM section. Round up if in between sizes.
  2. Stick close to your street shoe size:
    • if you are wanting a tighter fit, only go down half a size.
    • If you are wanting more comfortable shoes, go up half a size.
  3. Choose the UK sizing when ordering

Sizing feedback from Mitch:

Foot Profile:

  • Measured foot size: 253mm - rounded up to 255mm (6.5UK).
  • Cube style toes 
  • Average width.

Wearing a Bullit in 6.5UK:

  • My foot felt very snug.
  • Heel actively pushing toes into end
  • Minor pain on edges of toes after 30mins.
  • This is a comfy performance fit.

Wearing a Havoc in 6.5UK:

    • Foot still feels snug but less pushing in the toes as the heel in less pre-engaged.
    • Still feels somewhat of a performance fit.

Wearing a Fury in 6.5UK:

      • I struggle to get my foot in the shoe
      • Once I do, it's very tight.
      • Pain after 10mins in toes, particularly pinky toes.

Wearing a Ozone in 6.5UK:

    • Shoes are hard to get on, less difficult than Fury. 
    • Once on are more snug than the Bullits.
    • Pain after 20mins in the pinky toes.
    • This is a true performance fit.

Yes, I wear a lot of shoes...  back to top?
