Vancouver’s Casca Footwear has raised a $4.66 million venture funding round led by Khosla Ventures and including Shopify founder Tobi Lütke.

Casca also debuted its Avro sneaker model, which features a custom 3D-printed insole designed to create a more precise fit and comfort. Avro can be customized through Casca’s iOS or Android app and is printed according to arch and foot measurements. The shoes and custom-fitted insoles are then delivered to the customer within 14 days.

“At Casca, our vision is to set a new standard for the future of footwear,” said Casca co-founder Braden Parker.

“A big part of this is the way we manufacture. Casca challenges traditional manufacturing with a fresh approach that is customized, automated, and decentralized.”

The footwear startup plans to open its first retail space in Vancouver soon.
