In one chapter of the manga it's shown Tomura Shigaraki can disintegrate things with his feet. The disintegration activates apparently in the same way as the hands, when the 5 toes are in contact with the object. How does Tomura Shigaraki's power not disintegrate his shoes then?
The best guess would be socks with one hole for a toe. I am currently on that chapter so idk. I thought up until now that Tenko Shimura's (Tomura Shigaraki but we already knew this if we were this far) quirk could only be used through his hands. So this is a new development to me and pretty much all of us. Maybe the socks got damaged (If he wears special socks) during the whole fighting stuff or maybe when he disintegrated the building.
