Are these mules suitable for wearing outside?

They work for short dry-weather trips, but the suede upper and insole are vulnerable to rain, mud and pavement stains. For daily outdoor walking, a leather or rubber-soled mule holds up better.

How do I keep the suede clean?

Brush with a suede brush when dry and use a suede protector spray before first wear. Blot spills rather than rubbing, and let wet shoes dry away from direct heat.

Will they stay on my feet when I walk?

The backless design relies on the fit across the vamp, so they can slip off if the shoe is loose. The lace tie helps adjust the fit, but they are not made for fast walking or stairs.

Do they have arch support?

No arch support is described; the insole is suede, which is soft rather than structured. People who need cushioning or support should add an insert or choose a contoured footbed.
