“You're going to want to have a nice, comfortable pair of sneakers to walk around in.”
Your roommate is going on a trip to a foreign country for a few weeks, and you are helping her pack. You've been there before, so you're giving her advice. You think she should take a pair of athletic shoes to walk around in, so you say this.
You're going to want to have a nice, comfortable pair of sneakers to walk around in.
This expression is used to talk about something that a person doesn't want now, but you think they will want it in the future, when the situation is different. This is often used when someone is planning ahead for something, like a trip, and you're trying to think of what they will need in the future.
In normal conversation, "going to" would be pronounced "gonna".
The word "nice" and "comfortable" often come together to describe things like clothes, pillows, blankets, etc. "Nice" also frequently comes with a few other words:
- a nice, relaxing massage
- a nice, warm bath
- a nice romantic dinner
Sounds nice, doesn't it?
When you're talking about just one shoe, you can just call it "a shoe". When you're talking about both of the shoes, you have to call them "a pair of shoes". Other things that come in pairs:
- a pair of pants
- a pair of scissors
- a pair of glasses
- a pair of underwear
"Sneakers" are what athletic shoes are called in the U.S. They're also sometimes called "tennis shoes" or "running shoes". People from other English-speaking countries call them "trainers".
When you want to say that a person is wearing a pair of shoes while doing various activities, you say that they are "walking around in" them.
Notice that you use the word "in". Think of it as your foot being inside of the shoe.
