Why Fit Signature™

Built by Someone Who Knows How Shoes Are Made.

Fit Signature™ was created by Tori Soudan, a footwear designer with nearly two decades of immersion in Italian luxury footwear and the craft traditions of the Brenta Riviera.

After seventeen years of observing the same structural problem repeat across every collection, every fitting, and every return, she built the solution the industry was missing.

Fit Signature™ is not a technology company's interpretation of fit. It is a designer's answer to a problem she has lived.

Built on a proprietary structural analysis methodology

"I spent nearly two decades immersed in Italian luxury footwear, studying the craft traditions of the Brenta Riviera. I know exactly why shoes do not fit. Fit Signature™ exists because that problem has a precise, intelligent solution."

Tori Soudan, Founder

Your Fit Signature™ transcends geography. Shoe size changes by country. Your foot structure does not. When you travel, your Fit Signature™ speaks the same language everywhere — eliminating the confusion of converting between EU, UK, and US sizing systems. Your structure is the constant.

The Problem

Sizing Was Never Enough

Shoe size measures length. It does not measure structure. The result: footwear carries one of the highest return rates in fashion ecommerce — and fit is the single largest cause.

The Returns Crisis

The Solution

Structural Compatibility.

Powered by a proprietary methodology, the system evaluates foot geometry and shoe construction to determine structural alignment — telling you precisely which silhouettes will fit.

Every assessment evaluates your foot against the construction of the shoe. The result is a clear verdict. Built for your foot. Or not.

"Is this shoe structurally aligned with your foot?"

For Our Planet

Intentional Shopping. Less Waste.

Over 23 billion pairs of shoes are produced globally every year. When people buy the right shoe the first time, fewer shoes are returned, fewer are discarded, and fewer shipments are made. Fit Signature™ makes that possible.

"Intentional purchasing is not a constraint. It is a higher standard."
