脚跟用英语怎么说呢

脚跟用英语可以翻译为"heel"。
这个词源自中世纪英语中的"hele"，意思是"脚跟"。它最初是用来指脚跟鞋的，但是后来也用来指人的脚跟。
下面是一些例句：
She wore high heels, and the sound of her footsteps echoed through the hallway. (她穿了高跟鞋，脚步的声音在走廊里回荡。)
He leaned against the wall, resting on one heel. (他靠在墙上，只用一只脚跟着地。)
The dog was scratching at the door, its claws clicking against the hardwood floor as it dug in with its heels. (狗在敲门，它的爪子在硬木地板上发出咔哒声，用脚跟挖着地。)
