Lol. It's not what your wear on your feet. More important, is how you walk on the tiles & how much you weigh can make a big difference.
I only weigh 72kg for context.
Walk softly grasshopper; like you are walking on rice paper without making a mark.
I have a concrete tile roof, it's 30+ years old & I have lived here for 28 of those years. I walk on the roof a couple of times a year to check for storm damage, as I live in the mountains where the weather gets crazy sometimes.
I wear Blunstone steel cap work boots & I have never broken a tile by walking on them, I just take it slowly & spread the load across the tile.
~10 years ago we did an extension & I worked on the roof with the builder & his apprentice (apprentice weight estimated at 85kg). Neither me or the builder broke any tiles, yet the apprentice broke one almost every time he moved his feet. New tiles or old tiles, he could break them all. I told him to tread lightly, but he couldn't get it, just walked like an ogre, so I banned him from the roof after 1 hour & 10 tiles that I had to replace. Lucky I bought a whole pallet of tiles for the extension. Still have plenty leftover.
Hope that helps.
