Jump To Mitch's Experience wearing Ocun shoes

Tips for sizing your foot correctly:

Please note when measuring, it is on a bare foot without any shoes or socks.

Using a tape measure for best accuracy, measure from heel to longest toe and compare to the MM section. Round up if in between sizes

This measurement gives your high performance size

  • No upsize = high performance for sending climbs
  • Half size up = performance but more comfy
  • Full size up = All day comfort

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
  • Toes are bent
  • This is a 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 as it's a narrow model
      • Once I do, it's very tight.
      • Pain after 10mins in toes, particularly pinky toes.
      • For a narrow shoe, it's better to upsize half a size as I have a normal sized foot.

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?
