The short answer
Look for a leather loafer mule with a moc or apron seam and a vamp that reaches the instep. A bit (the metal bar across the top) dresses it up; a penny strap or plain vamp keeps it quiet. For a famous reference point, the Gucci Princetown is the backless horsebit loafer most others are compared with.
Why loafer mules work
A loafer has a high vamp by design, and a high vamp is exactly what holds a backless shoe on. That makes the loafer mule one of the easiest mules to walk in, and the one most likely to pass for a closed shoe at the office.
The details that matter
Loafer mule details
| Detail | What it is | Effect |
|---|---|---|
| Bit (horsebit) | A metal bar or link across the vamp | The dressiest version; the gold or silver reads as jewelry |
| Penny strap | A leather band with a slot across the vamp | Classic and quiet |
| Moc or apron seam | The raised stitched seam around the toe | Gives structure and a true loafer look |
| Lug or platform sole | A chunky sole | More casual, a little height, heavier |

Fit
Loafer mules usually run closer to your normal loafer size than to a sandal size. Your heel should land fully on the footbed and the vamp should feel snug at the instep. If a brand only sells whole sizes and you are a half size, try the smaller size first, and keep the box until you have walked in them indoors. More in how mules should fit.
What to wear with loafer mules
- Tailoring: straight or cigarette trousers that end at the ankle.
- Denim: straight-leg or slightly cropped jeans with a crisp shirt.
- Skirts: a midi skirt and a fine knit; add sheer socks in cold months if you like the look.

Questions people ask
What is a backless loafer called?
A loafer mule, a backless loafer or a loafer slide. They all describe the same shape: a loafer front with no heel counter.
Are loafer mules professional?
In most smart casual and business casual offices, yes. Choose smooth leather in black, brown or burgundy and a quiet sole. See our mules for work guide.
Do loafer mules slip?
Less than many flat mules, because loafer vamps are usually cut higher over the foot. If yours do, the length is probably too long; a heel grip under the vamp can help a small gap.
