A little while ago, I bought a very cheap pair of canvas pumps online and used a scalpel to cut out two big holes in the bottoms of them. Then I put them on without socks and went for a 10-minute walk to the shops.
It was quite painful since the concrete had been baking in the sun for a while and I occasionally stepped on a small rock or a twig but it did make the soles of my feet absolutely filthy.
When I got back home, I put the camera on the floor of my room and filmed a short video to show off just how dirty my soles had gotten, enjoy!
If you have any suggestions for what else I should do with these soleless shoes, leave a comment or feel free to email me at firstname.lastname@example.org
