IVY: I want to buy some running shoes. Maybe New Balance.
DAVID: Why do you need running shoes? You aren't a runner.
IVY: But I exercise at the club. And I use the stepping machine.
So I need good running shoes.
DAVID: That's not the same.
Maybe you want to buy running-shoe-style shoes, but not real running shoes.
IVY: What's the difference?
DAVID: There isn't much difference. But there is some difference.
For one thing, real running shoes are much more expensive.
They have very lightweight materials.
They're designed for serious runners, people who run ten kilometers a day.
IVY: And what are running-shoe-style shoes?
DAVID: They look like running shoes.
They have the same shape. And you can use them for running too.
But they're not so serious. They aren't designed for serious runners.
You can use them for exercising.
IVY: But they aren't as light, right?
DAVID: That's right.
If you want a really lightweight shoe, you should buy a high-quality running shoe.
IVY: That's what I want.
For exercising at the club. I can even spend 100 dollars on them. I don't care.
DAVID: But it's a waste of money. You won't really run in them!
You don't need such a shoe to use exercise machines. It's just a waste of money.
IVY: My sister has New Balance running shoes. I want shoes just like hers.
I don't care if they're expensive. And they look cool too.
DAVID: Well, do what you like.
There are different kinds of New Balance shoes though.
You don't have to buy the most expensive.
IVY: I want the best.
My sister said good shoes are very important. For support. They support your feet.
DAVID: Your sister is a fitness expert, huh?
IVY: No, but she exercises more than me.
DAVID: I really think you are stubborn about some things.
But here. Let's look at the New Balance shoes.
IVY: Here it is. This is what my sister has.
DAVID: Yes, that's it. That's their top model.
IVY: I wonder if they have my size.
DAVID: Well, we can wait for the assistant to help us,
or we can look through the boxes down here. What is your size?
IVY: Here in America, it's six.
DAVID: Well, here you are. Size six. Woman's. 137 dollars.
Wow, what a waste of money!
IVY: It's none of your business. Let me try them on.

艾薇：我想买跑鞋，纽巴伦牌子的。
大卫：你为什么需要跑鞋？你又不跑步。
艾薇：但是我在俱乐部运动，而且我用踏板的器材。
所以需要好的跑鞋。
大卫：那不一样。
也许你想买的是跑类的鞋子，不是真的跑鞋。
艾薇：有什么差别吗？
大卫：没有太大差别，但有一点点差别。
差别在于真正的跑鞋贵很多，
它们的材质很轻，
是为热衷跑步的人设计的，一天跑十公里的人。
艾薇：那什么是跑类的鞋子？
大卫：它们看起来像跑鞋。
外观一样，也可以用来跑步。
但是不是专门的，不是专门为跑家设计的。
你可以用来运动。
艾薇：但是没那么轻吧？
大卫：没错。
如果你想要很轻的鞋子，就要买高级的跑鞋。
艾薇：我就是要那个。
为了在俱乐部运动，我甚至可以花 100 美元买鞋，我不在乎。
大卫：那太浪费了，你又不是要跑步！
你不需要买这种鞋来踩运动器材，那只是浪费钱罢了。
艾薇：我姐姐穿纽巴伦的鞋子，我就是想要她那种鞋子。
我不在乎贵不贵，而且看起来也很有型。
大卫：好吧，只要你喜欢。
纽巴伦的鞋子有很多款式。
你不必买最贵的。
艾薇：我要最好的。
我姐姐说买双好鞋是很重要的，要用来支撑，支撑脚部。
大卫：你姐姐是健康专家啊？
艾薇：不是，但是她比我常运动。
大卫：你在一些事情上真的很固执。
在这里，来看看纽巴伦的鞋子吧。
艾薇：这就是我姐姐穿的。
艾薇：不知道有没有我的尺寸。
大卫：你可以等店员过来帮忙。
或是我们找底下的盒子看看。你穿什么尺寸？
艾薇：在美国是六号。
大卫：这里有，六号，女鞋，137 元。
哇，好浪费钱喔！
艾薇：不关你的事，让我试穿。
