Can AI handle shoe sizing questions, including half sizes and width?

Yes — a 9.5 in wide is a specific variant, and Sauzy checks your live Shopify inventory at the variant level before confirming it's available, rather than answering from a memory of the range.

Will automated sizing advice raise my return rate?

Not if it's honest. The assistant gives real fit guidance — 'these run small, size up half a size' — instead of reassuring a customer into the wrong size, which is where footwear returns come from.

Can it convert a 'do these run true to size?' question into a sale?

Yes — it answers the fit question accurately, then links straight to the correct size and width, pre-selected, so a keen buyer doesn't cool off hunting for their size on a generic product page.

Instagram DMs for Footwear & Shoe Brands: Sizing, Fit, and Width Questions That Convert

20 September 2026

Footwear is one of the hardest categories to sell confidently online, and the reason is entirely sizing. A shoe isn't a rough fit like a t-shirt — half a size out is the difference between a keeper and a return. So the DMs a shoe brand gets are dense with sizing anxiety, and how well you answer them decides both your conversion rate and your return rate at the same time.

The questions a footwear buyer asks

Size and half-size availability. "Do you have these in a 9?" "Is the 8.5 sold out?" Per-variant stock, and the most common message you'll get.
Fit and sizing conversion. "Do these run true to size?" "I'm usually a US 9 — what do I order?" "Should I size up?" Sizing conversions and fit guidance carry real return-cost consequences.
Width. "Do these come in wide?" "Are they narrow?" A make-or-break question for a big slice of buyers that generic replies ignore entirely.
Materials and comfort. "Are they leather?" "Is there arch support?" "Are they good for standing all day?"
Restocks. "When's the 10 back in?" — a captured size intent worth chasing.

Sizing accuracy is your return rate

Every category has a "fast vs accurate" tension, but footwear is the one where being carelessly reassuring is most expensive. Telling someone "yeah, order your normal size" to close the sale faster, when the shoe actually runs small, doesn't lose the sale — it defers the loss to a return two weeks later, and returns are the cost that quietly eats footwear margins. Honest fit guidance ("these run small, size up half a size") converts slightly slower and costs far less.

Half-size and width availability is a variant problem

A 9.5 in wide is a specific variant, and answering "yes we have it" from a memory of the range rather than current stock is how a promised pair turns into a cancelled order. Any availability answer has to check stock at the variant level, at the moment of reply — the same discipline we covered in Handling out-of-stock questions on Instagram.

Close on the exact size, not the product page

When a buyer has landed on their size and width, the sale is one link away — but only if that link goes to the exact variant, pre-selected. Sending them to a generic product page to hunt for the 9.5-wide again is where a keen buyer cools off. (More on that hand-off in Checkout inside Instagram DMs.)

Where this gets hard by hand

Answering one sizing question well is easy. Answering every one accurately — the right size conversion, the real width availability, the current stock — across every DM and comment is where manual replies drift, and in footwear that drift shows up directly in your return rate. That's what Sauzy is built for: it answers from your live Shopify catalogue at the variant level (so a sold-out half-size is never promised), gives honest fit guidance, links straight to the right size when someone's ready, and hands anything unusual to you.
