Shoe fit involves more than checking where your longest toe ends. Arch length, also called heel-to-ball length, is another measurement worth discussing when a shoe seems long enough but still feels wrong.
The Brannock Device instructions distinguish heel-to-toe length from arch length and explain how to compare them when selecting a starting shoe size (Brannock fitting instructions). The measurement helps guide a fitting, but trying on the actual shoe remains essential.
What is arch length?
Arch length measures from the heel to the ball joint of the foot. On a Brannock Device, the sliding arch indicator is positioned against that joint, rather than at the end of the toes (Brannock).
Do not confuse arch length with arch height. For your fitting conversation, ask about heel-to-ball position as well as overall length, width, and how the shoe feels when you walk.
Why compare two length measurements?
Brannock's instructions generally use the larger of the heel-to-toe and heel-to-ball measurements as the starting size. The instructions also call for measuring while standing with weight distributed equally across both feet (Brannock).
This is a reason not to decide fit from toe room alone. It is not a promise that a particular printed size will work in every brand or style.
The American Academy of Orthopaedic Surgeons notes that sizing varies and recommends choosing shoes based on how they fit, not just the number on the label (AAOS fit guidance). Compare the complete fit before buying.
A practical fitting checklist
Bring the socks you intend to wear and any prescribed orthotic your clinician has recommended. Then compare these points while standing and walking:
- Length: Notice whether your toes feel crowded at the front.
- Width: Check for pressure across the ball of your foot.
- Heel security: Watch for repeated lifting or rubbing as you walk.
- Overall feel: Tell the fitter where you feel pressure rather than assuming discomfort will disappear.
If the length feels adequate but the sides feel tight, a wider option or different toe-box shape may be more useful than simply increasing length (AAOS). Our women's wide-width fit guide explains what to compare.
Common questions about arch length
Does measuring my feet replace trying shoes on?
No. Use the measurement to narrow the starting options, then stand and walk in both shoes before deciding.
Does a strong arch sensation mean the fit is correct?
Do not use that feeling as your only test. Compare toe room, heel hold, and overall comfort together; our comfort-versus-support guide offers a useful starting framework.
