Lodičky, or Calling All Shoe Experts

There is a section in Jaroslav Seifert's memoirs in which he describes his early encounters with Toyen. First, he'd see an intriguing figure in rough work clothes going by on the street--apparently she was working in a soap factory. Toyen next appeared in his life when she came to join the Devětsil group. At this juncture she was rather fashionably dressed, wearing a type of shoe known as lodičky ("little boats").

Štěpanka has enlightened me that the term lodičky refers to shoes without straps or buckles, which one just slips on and which are... sort of boat-shaped. They may or may not have high heels; the important factor is that most of the top of one's foot is exposed.
I've certainly owned shoes of this type, but I have no idea at all whether they have a name in English. Any ideas how to translate this?

And then, there are also střevičky, which I haven't yet figured out, but which led me to this interesting site for reproductions of historical footgear and saddlery! Click on Shoe and you'll find a vast selection of gothic, Renaissance, and baroque shoes. I am very tempted, but this doesn't translate lodičky or střevičky for me...
