Measured in AskSpot over a 30-day window. Casu sells footwear people can’t try on, so the whole sale hinges on fit — and the chat turns fit questions into carts and chat-driven orders, clearing seven in ten conversations with no human.

Before AskSpot

Shoes are bought by fit, and mostly in the evening

Nobody buys shoes online the way they buy a T-shirt. The customer is picturing one foot — 25 centimetres long and a little wide, a bunion that a stiff court shoe will press on, a pistachio to match a dress already hanging in the wardrobe. The real questions are whether this exact pair fits that foot and whether the colour is right in the flesh. A product page prints a size chart; it can’t tell a shopper whether a 39 in this model will actually be comfortable.

Casu makes much of what it sells, so fit is specific to each last — a wider strap here, a softer leather there, a size that runs true in one model and snug in the next. Those are judgement calls, not clicks, and every one of them used to end at a product page that couldn’t make them, or in a message sent long after the shop had closed — which is when most of them arrive.

Rollout

How Casu rolled out AI chat

One module, set up in the order a shoe purchase actually happens: get the size right first, then the fit and the look, then keep the sale when the size a shopper wants is gone.

Step 01

Catalogue & Size Grounding

Answering with the tape measure out

The IdoSell catalogue was indexed on the numbers that decide a shoe purchase — insole length in centimetres against each EU size, the width of the last, heel height, upper material — so the agent turns “my foot is 25 cm” into the right size in that exact model, not a generic size chart.

What shoppers ask

  • My foot is 25 cm and a bit wide — what sandal size should I take?
  • Trekking sandals in a 42, insole length 27 cm — do these fit?
  • Is the width given for the heel on these block-heel sandals?

Step 02

Fit, Materials & Style Advice

Wide feet, bunions and the right shade

The materials and fit notes were given their own rules — which lasts run wide, which leathers ease over a bunion, what a colour looks like next to an outfit — so the agent recommends a pair that will actually be comfortable, matches a shade to a dress, and adds the right size to the cart.

What shoppers ask

  • Are these court shoes OK for a wider foot? I have bunions.
  • I’m after shoes in pistachio, low heel, to go with a dress.
  • Will these boots be too narrow on a wide calf?

Step 03

Stock, Delivery & the Honest Alternative

Keeping the sale when a size is gone

Live stock and delivery were wired into IdoSell, so “when does it arrive?” returns a real dispatch window, InPost-locker and courier options, and cash on delivery. When a size is out with no confirmed restock date, the agent says so plainly and offers an in-stock pair in the same style — rather than promising a date it can’t keep.

What shoppers ask

  • Will size 39 of these black boots be back in stock?
  • Do you ship to InPost lockers? Can I pay cash on delivery?
  • Can I swap for another size instead of returning?

From real conversations

What Casu shoppers actually ask

Almost every question is one shopper solving the thing a website can't: will this shoe fit, and will it look right. Product advice and specs lead — and read closely, both are really about fit: foot length in centimetres, a wider or narrower last, room for a bunion. Delivery terms, returns and stock follow. It's a fitting room, staffed by chat.
