Walking barefooted is very bad to me because it will increase the chances of micro organism to penetrate into the feet that will cauee numerous diseases.

We came to this world barefooted and will obviously leave the same...

The reason for the creation of foot wears is for the protection of the feet against possible dangerous infection which may be caused by cuts or invasion of microorganisms....

Imagining The world without foot wears (being barefoote ) will be really strange as yuu mentioned. Although in the olden days humans walked on bare foot before the introduction of the foot wears. It will be more strange because the world has experienced the impact of footwear so to avoid it will be kind of not easy....

Thanks for sharing and good luck with the challenge
