Pairs of shoes are created symmetrically.

our feet are not.

Feetium’s proprietary shoe-fitting system goes beyond comparing dimensions of shoes and feet. Feetium turns mass-produced shoes into customized shoes at the point-of-sale, thus enabling better comfort and performance for symmetrical and asymmetrical feet

To achieve fitting that affords greater performance and comfort, Feetium addresses the problem of asymmetry that affects more than ⅓ of customers worldwide.

The largest dimensional variance between feet lies in the girth/circumference/volume of the forefoot, making it the primary factor when addressing asymmetry between left and right feet.

Feetium enables consumers to customize their fit through a set of adaptive insoles that replace the standard insoles supplied with shoes.

Adaptive insoles are mass produced and have the same shape as the original insoles, but vary in forefront thickness to achieve optimal volume in each shoe.

“Adapt to Comfort algorithm”

The Feetium algorithm appoints the most accurate size in a shoe model selected by a customer and corrects the forefront volume/width with adaptive insoles as needed to achieve the optimal fit for each foot.
The Adaptive insoles are color-coded:

Blue – a thin insole, to increase the volume/width of the shoe (for a wide foot)

Red –  a standard insole

Green – a thick insole, to decrease the volume/width of the shoe (for a narrow foot

A deeper look into Customization

How do adaptive insoles adjust the volume/width inside the shoe?

In layman’s language, adaptive insoles “increase or decrease the width” of the shoe.

The thicker adaptive insole reduces volume in the shoe for narrow feet, while the thinner adaptive insole increases volume in the shoe for wide feet.

For each shoe model selected by the customer, Feetium’s “Adapt-to-Comfort Algorithm” offers the optimal combination of shoe size and adaptive insole per foot.


Shoes are paired with adaptors on an individual basis, not per pair. Therefore, as each shoe can be outfitted with one of three adaptors, that ultimately translates to 3 * 3 = 9 fitting options for each pair of shoes, giving customers an unparalleled experience in terms of fit and performance.


Retailers also gain substantial advantages in inventory management due to the ability to modify shoes for specific fitting variations, reducing walked sales without expanding in-store stock.


Asymmetric Feet Globally
