Having been a person that works on my feet for 8-10 hours a day I can safely say I could wear bricks on my feet..
However most of you will have soft well manequred feet.. (well at least I would hope so ladies)
it it really comes down to common sense. If you are not comfortable you won’t be happy to ensure that you choose something that feel cumfortable for at least 2-3 hours.. try wearing them around the house.
And if all else fails.. take them off it’s your day.. just relax.
