Wearing high heels for a long period of time is no easy feat. Your muscles have to work harder than normal, and more weight is pushed to the ball of your foot which can cause them to be sore.
But it's understandable that not everyone can relate to the type of tiredness caused by wearing high heels.
One man sparked a massive debate after admitting he had refused to give up his seat on the bus for his girlfriend whose feet were tired after walking around cobble stone paths for an hour.
The 26-year-old, who said he was also "tired and quite breathless still", said his girlfriend, who was wearing stiletto heels, told him he was being "inconsiderate" – and many people agreed.

Taking to a forum on Reddit, the man explained: "My girlfriend and I went out for a special event and we were both very dressed up."
They took the bus to the event, and on the way back they both decided to do some errands in the city and spent "a good hour walking around".
He continued: "The city is hilly with older cobble stone paths and this was quite tiring for me as I'm not the most fit. When we caught the bus to go home, I entered the bus first and took the last available seat and my girlfriend [sic] stood next to me."
When the bus started moving the 27-year-old girlfriend asked if she could take the seat because "her feet were tired".
The man, who remained anonymous, continued: "I declined as I was tired and quite breathless still.
"When we got home she said I was being inconsiderate since she was in heels. I didn't really think that's relevant since she almost always wears heels, but she said those were stilettos and she normally wears block heels, but I don't really know the difference and I didn't think it mattered for standing, maybe for walking.
"She is more fit and goes to the gym and has more stamina and it was just her feet that were tired so I feel I deserved the seat more. Besides it was her choice to wear the shoes."
The man caused outrage on the forum, with many people shocked he didn't have sympathy for his girlfriend and wasn't willing to give up his seat for her.
One person said: "If your girlfriend had been in stilettos the whole time and doesn't usually wear stilettos, there's a good chance that she was in quite a lot of pain. Like burning the bottom of her feet pain.
"Also, there can be huge differences between wearing stilettos and block heels. Also, balancing on a moving bus in stilettos? F*****g hell. I wear them a lot and would still struggle if my feet were already fatigued."
Another commented: "Try on a pair of heels, then walk in them for an hour. At the very least you could have let her sit in your lap or taken turns sitting. Pretty sure you won't have a girlfriend for long."
"Obviously trading off half way home would have been a fair compromise. You would have been able to catch your breath and she would have a chance to get off of the heels. Or she could have sat on your lap or vice versa. What you did was selfish," commented a third.
