Let your customers feel how shoes fit

Fit visualizer card for US M 9 showing the snug-to-roomy fit across both feet
Two shoe lasts of the same size. The left last has a rounder, wider forefoot. The right last has a sharper, narrower forefoot.

Two lasts, same size. The left has way more forefoot volume than the right.

A size label doesn't measure fit

Every shoe is built on its own last, and materials and design choices change the fit too. So the same size can feel very different from brand to brand, or even model to model. Shoppers can't tell from the label, so they exchange or return the shoes (or worse, don't buy at all).

MatchUp scans the shopper's feet with a phone and shows how each size will feel. The shopper picks the size that feels right for them.

How setup works

Setup is simple. We only need two things from you: a photo of your shoe and a scan of your feet. Then try the shoe on and tell us which size feels the way you want your customer to feel. We use that to work out the shoe's last and the details that matter for fit, and compare them with each shopper's feet.

That way, the size your shoppers are encouraged to buy is the size that feels the way you meant it to.
