How to Measure

Use a soft measuring tape and keep it level and snug — not tight.

Bust / Chest

With arms relaxed at your sides, measure around the fullest part of the chest or bust.

Waist

Measure around the natural waistline — the smallest part of the waist.

Hips

Standing with legs together, measure around the fullest part of the hips.

Inseam

Measure the inside length of your leg from the crotch down to the bottom of the ankle.

Choosing Your Footwear Size

Sizing is based on arch length

The orthotic footbed is built around the heel-to-ball measurement rather than heel-to-toe, so the arch support lands in the right place. Your size may differ from other brands.

Between two sizes?

Measure the longer foot — most people have slightly different-length feet. Adjustable straps handle the rest of the fit.

Width

Footwear is offered in medium and wide. Width is marked at the heel: dots indicate medium, dashes indicate wide.

Strap styles

No-loop straps give a more relaxed fit and suit higher arches or sensitive toes; toe-loop styles add security on uneven ground and in water.

Fit guarantee: if the product doesn't fit quite right, exchanges are free.

Care & Returns

  • Returns: unworn, unwashed and unaltered items can be returned within 30 days.
  • Exchanges: free exchanges on any item that doesn't fit quite right.
  • Custom orders: personalized and custom-built footwear is made to order and is not returnable or cancelable.

Footwear conversions follow standard US / UK / EU / JPN charts. Measurements are approximate and provided for reference only.
