Sizer Plugin Demo

This page shows demo integration of the Sizer size advisors. It can be integrated into a regular text page next to size tables, or directly into a product page with automatically loading the currently shown product to find the size for the shoe.

Click any ‘Find my size’ button below, to see the Sizer in action!

Each example below shows which options are switched on — and under them, a realistic use case. The buttons and pages are the shop's own design; the advisor adapts its colors, language and flow to the chosen options.

Size Guide Page (Example #1)

The advisor on a regular text page, next to a size table — the visitor picks the shoe themselves.

Shoe Size Guide

Sizes differ between brands — the same foot can need a different number in each of them. Use the table below to convert between systems, or let our size advisor recommend the right size from a shoe you already own.

41 7 8
42 8 9
43 9 10
44 9.5 10.5

Conversion values are approximate and vary by brand.

No manual brand or category mapping: the barcode is data the shop already has in its product feed. This is also how ShoeGuru's product pages preselect the exact shoe.

When a visitor completed an advice run before, Sizer remembers the profile and answers directly on the page — the line below appears without a click.

Inline Embedding (Example #5)

The advisor mounted in the page flow of a content article — no popup, no button. Used on ShoeGuru's guide and product pages.

Why So Many Shoes Go Back — and How to Buy the Right Size Online

Buying shoes online is convenient — until the box arrives and the fit is wrong. Wrong sizes are the single biggest reason shoes are sent back: the same foot needs a different number in almost every brand, and a size label alone doesn't tell you how a shoe actually fits.

Every returned pair is shipped twice, repackaged, and sometimes never sold again — a cost for the shop, a hassle for the customer, and unnecessary emissions for everyone. The most effective fix is simple: get the size right the first time.

A size advisor closes the gap. You tell it one shoe that fits you well — brand, model, size — and it translates that fit to the shoe you're looking at, using real sizing data instead of a generic conversion table. No measuring tape, no guessing between two sizes, fewer boxes going back.
