Show fit read-outs (width, length, overall fit) on reviews

Above the reviews, three sliders aggregate how buyers rated width, length and overall fit, answering the sizing objection with other customers' data.

What it is

The reviews section opens with the star average and three slider read-outs aggregated from reviewers: Width (tighter to wider), Length (runs smaller to runs larger) and Overall fit (bad to good). Individual reviews below carry a verified-customer tick and a size filter.

Why it works

A star rating says whether people liked the product, not whether it will fit you. Fit sliders turn reviews into a sizing tool built from real buyers, which answers the most expensive objection in footwear and apparel without the brand having to make a claim at all.

How to test it

Hypothesis
Adding aggregated fit read-outs to the reviews section will lift add-to-cart rate and lower size-related returns.
Primary metric
Size-related return rate
Guardrail metric
Review submission rate, since asking for fit ratings adds fields to the review form
