On July 12 KST, Red Velvet appeared at Incheon International Airport on their way to Kaohsiung, Taiwan, to attend 'K-MEGA CONCERT IN KAOHSIUNG'. 

On this day, member Seulgi wore a chic black outfit, accented with a pair of gray heels. 

But later, when the members of Red Velvet landed in Taiwan, Seulgi was spotted at the airport in sneakers instead of her gray heels. 

Fans soon noticed that Seulgi had changed shoes with a female manager, who had been spotted at Incheon Airport in the same pair. 

In fact, the manager was seen exiting the airport in Taiwan wearing Seulgi's heels, confirming that the two had traded shoes some time before landing. 

The issue has now become a hot topic on an online community, in light of the recent buzz around celebrities and their "master-servant" relationship with their staff. 

Some K-netizens commented,

"It's does seem a little like the manager is getting the short end of the stick."

"If a celebrity complains that her shoes are hurting her feet, can a manager or staff member refuse to switch shoes with them?"

"If she wanted to switch to more comfortable shoes later on, she should have packed her own shoes... Why does the manager have to give up her shoes?"

"Even if the staff volunteered to switch with her so Seulgi wouldn't hurt her ankles, it's still a situation involving one side in power and another side under subordination."

"If she thought the shoes would give her problems, she should have asked for them to prepare an extra pair of shoes beforehand."

"Why can't they buy her a pair of shoes at the duty free shop? This definitely doesn't look good for Seulgi."

However, others argued, 

"No one knows the full story so it's hard to say for certain that the staff was 'forced' to switch shoes with her."

"But a manager's job is literally to take care of the artists. They don't want her to accidentally hurt her ankle and not be able to perform."

"It's not that serious, and no one knows what the actual situation was so stop speculating."

"If my friend had something important going on the next day, and she had to wear uncomfortable shoes, I would switch with her for a little bit to help her out."

"If the manager volunteered to do that for the artist, who are we to judge and speculate?"

"There's no reason to make a big fuss about this. It's not like Seulgi has had attitude problems in the past. If people start making a big deal about this and the fans try to defend her, it will actually give people excuses to turn this into something much bigger." 

"It's best to not make any unnecessary speculations. They could have had plenty of reasons why extra shoes weren't prepared in advance."

Meanwhile, Red Velvet most recently released their 9th mini album, 'Cosmic', along with a title track of the same name.
