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?

I have made the move from Scarpa Helix to these Ocun Havoc shoes. The softer rubber on these Havocs enable me to feel more certain and secure of my footing.
I could not be any happier - Sophie was amazing and helped me in getting the best fit possible. I will certainly be back to Happy Biner and have already recommended them and the Havocs to others at my bouldering gym.

Bought these as my first pair of climbing shoes. They have been great - very comfortable and grippy.

A super comfortable and durable shoe for all day climbing. Works well on all kinds of climbing definitely a well-rounded shoe. The heel fits me really well, unlike some other shoes I have tried that do a similar job. For sizing - in these shoes I wear the same size as my street shoe, an 11. I haven’t worn these super tight like a comp shoe.
