onefit.ai

onefit.ai helps shoe retailers cut returns by letting shoppers scan their feet with a phone and get a size recommendation for each brand and shoe type. It installs as a Shopify plugin and is made by a London company.

Shoppers follow a short scan in place of measuring tapes and size charts, and the system returns millimetre measurements and a recommended size. Because sizing differs between brands, it translates the measurements into each brand's own fit.

Plans are based on how many foot scans your store uses each month, with a free starter tier and a per-scan charge once included scans run out. A calculator on the pricing page estimates costs from monthly visitors.
