Company profile

researched Aug 2026

SOLS is a footwear technology company founded in 2013 that produces custom 3D-printed orthotic insoles. Customers or clinicians capture a few photographs of a foot, from which SOLS builds a three-dimensional model and manufactures a corresponding insole; the product is printed and shipped within about a week.

The company initially distributed through medical channels, supplying insoles to patients of physical therapists, podiatrists and orthopedic doctors, and later moved to sell directly to consumers with an emphasis on sports applications. SOLS has also prototyped a 3D-printed shoe called ADAPTIV, described as combining a 3D-printed exoskeleton, color-changing LEDs and inflatable internal cells intended to respond to movement and biomechanics.

Founding story

SOLS was founded in 2013 by Kegan Schouwenburg and Joel Wishkovsky. Schouwenburg, who serves as CEO and has a background in design and fashion, was previously director of industrial engineering and operations at the 3D printing marketplace Shapeways, where she conceived the idea for SOLS while on the factory floor.

Business model

SOLS manufactures custom insoles on demand from digital foot scans. Distribution originally ran through a network of medical professionals who provided SOLS products to their patients; with its Series B the company moved to add direct-to-consumer sales of 3D-printed footwear products, positioned as making its technology accessible at an affordable price.

Traction

As of February 2015, SOLS had 45 employees, a network of 300 medical professionals providing its insoles to patients, and $19.3 million raised since its 2013 launch.

Latest developments

In February 2015 SOLS announced an $11.1 million Series B round and said Terdema Ussery, president and CEO of the Dallas Mavericks, would join its board of directors. The company presented its ADAPTIV shoe prototype in connection with an NBA All-Star Weekend and Fashion Week wearable-technology showcase organized with Melo7 Tech Partners.

The company has also experimented with robotics and biomechanics in its ADAPTIV shoe prototype, including inflatable cells intended to detect and respond to movement.

Go-to-market

Patients of physical therapists, podiatrists and orthopedic doctors served through a network of about 300 medical professionals, plus consumers, including athletes and recreational users, targeted through the company's direct-to-consumer expansion.
