Fit check

Tell us your
millimetres first.

We can't let you try them on and send them back. That's why we give you the millimetres before you buy. We would rather talk you out of a pair than have you open a sealed pack you cannot return.

What you get back.

  • The specific items that sit below your opening, named, with the clearance each one leaves in millimetres.
  • A warning where the margin is under 5 mm, because that margin disappears the moment the shoe flexes.
  • A silicone-free alternative for anything we suggest that has silicone in it.
  • An honest no, if the honest answer is that nothing we make suits your shoe or your heel.

Your data

Shoe openings and heel shape are kept for 6 months, used only to answer this question, and never used to build a profile. Privacy notice

What we do not promise

No sock stays up in every shoe on every foot. Cuff height, heel shape, how the shoe fits and how you walk all matter. We give you the measurements so you can compare them to your own shoes.

mm

Measured from the surface the shoe rests on up to the lowest point of the opening at the back. How to measure it

Describe it in your own words. Please do not give us a brand name; the measurement tells us more than the label does.

Your heel
Is silicone acceptable

Heel to longest toe, standing. More reliable than the size printed in your shoe.

If you have not measured yet.

  1. 01

    Stand the shoe on a flat surface

    A table or a floor. Not a rug, not a shoe box. The measurement starts at whatever the sole rests on.

  2. 02

    Find the lowest point of the opening at the back

    Follow the collar of the shoe round to the back. Where it dips lowest is the point that decides whether a sock shows.

  3. 03

    Measure straight down to the surface

    Hold the rule upright against the outside of the heel. Read the millimetres. That single number is what we need.
