The Attico Mules: Betta, Ada and Irmelin Compared, with Heel Heights and Fit

Mules are the easiest heel The Attico makes: no straps, no buckles, slipped on for dinner. Coveti carries 3 styles, $1,360 to $1,840, including the new Betta from the anniversary capsule Superattico10. This page compares them on heel height, fit and occasion, and explains how to wear a backless heel without it slipping.

Betta

Betta Crystal Mules in Grey Satin is the new mule. It is cut in grey satin and covered in heat-applied crystals, with a peep toe and a heel that curves slightly inward, 9.5 cm high. The house describes the fit as relaxed and recommends your usual size, which matters on a backless shoe: a mule that is too big will slap at the heel. Insole and lining are goat leather, the sole is leather, and it is made in Italy. It is the one to wear with the anniversary dresses.

Ada and Irmelin

The other two come from earlier seasons. Ada is a pointed mule on a slim heel, the most classic of the three. Irmelin is a platform mule on a 140 mm heel, the highest, and built for the house party look. Both are in the product list below with their prices. Choose Ada for dinners and the office party, where you stand and walk a lot, and Irmelin for nights where the shoe is part of the outfit and you will mostly be sitting.

How to wear mules

Mules work with anything that shows the ankle: cropped tailoring, a slip dress, a mini. With the robe mini dress the Betta is the obvious match. Keep the leg bare and avoid heavy tights, which make backless shoes slide. how to wear black heels has more on heel proportions.

Sizing a backless heel

A mule has nothing at the back to hold the foot, so fit is everything. Your toes should reach the front edge of the sole without hanging over it, and your heel should sit on the heel cup with no more than a finger of space behind it. If you are between two EU sizes, choose the smaller for a mule, because the foot always slides forward on a heel. The Attico lists Betta in whole EU sizes 36 to 41; half sizes exist at source but Coveti lists the whole sizes the house makes. For the house size chart and how Italian shoe sizes convert, read The Attico shoe size guide.

Crystal care

Heat-applied crystals are bonded to the satin, not sewn, so they are durable but not indestructible. Store each mule in its own dust bag so the crystals do not rub against the other shoe, keep them away from water, which marks satin, and wipe the sole after wearing. Do not put them near a radiator, as heat can loosen the bond.

Mules against slingbacks

If you want the open heel with more security, the slingback is the halfway house: the Cheope slingback has a strap at the heel and the house sculptural wedge. The Attico heels and slingbacks covers the full range.
