自度其足,这个“度”应该度（duó）：量长短.下文的 勿忘尺度 的“度”念度（dù)：量好的尺码.因为两个度的意思不同,词性也不同,一个是动词,后一个是名词.
郑人有欲买履者,先自度其足,而置之其坐.至之市,而忘操之.已得履,乃日："吾忘持度."反归取之.及反,市罢,遂不得履.人日："何不试之以足?"曰："宁信度,无自信也."
意译：
有个想买鞋子的郑国人,他先度量好自己的脚的尺寸,然后把它放在了自己的座位上.准备去集市时,忘了拿量好的尺寸.他在集市上选好鞋子后,才想起自己忘了拿尺寸,他说：“我忘带鞋子的尺寸了.”于是返回去取尺寸.等到他返回集市的时候,集市已经散了,最终没买到鞋.有人问：“为什么不用你的脚试一试呢?”他说：“我宁可相信量好的尺码,也不相信自己的脚.”
