This kind of women's footwear is called in english mules, slippers, slip-ons, mule shoes or even clogs. In Italy they are called mules or better sabot if they have closed toes. Both are french terms, I don't know about other languages.

With high stiletto heels or kitten heels mule slippers can be evening footwear, if made in luxury satin and embroidery. If made in leather they are perfect daytime shoes, with pants but also with skirts. These models have an aggressive sporty line of western inspiration, being an alternative to the soft and romantic seasonal trend. They are always in great fashion either in summer or in winter.

Although this particular design is a little old, we expect that this kind of sporty mules and clogs would remain fashionable, together with western boots and booties of Texas or Tex-Mex inspiration.
