stack heels是什么意思

只查到是印刷跟的意思，不明白
原句是这样的Short people should pray for a return to the Seventies fashion of stack heels.
还查到stacked heel是叠跟，怎么理解叠跟？句中的stack heels又怎么理解？
谢谢！

似乎有点像“平底高跟鞋”
看看这一段解释
A stack heel is a specific type of women's shoe. Like many women's shoes, a stack heel has a protruding design element at the back of the shoe which causes the wearer to look taller. In addition to increasing height, heels also change the way that the wearer moves and walks, sometimes in an aesthetically pleasing way. Stack heels are distinguished by their typically more chunky look, and their greater degree of comfort when compared to some other heeled shoes. Like other heeled shoes, learning to walk on a stack heel takes time and patience.

我第一印象是“松糕鞋”，但结果发现不是的。

无满意结贴吧
