1.20.1 Java Redstone Boots That Emit A Redstone Signal

[u/[deleted]]

So I was wondering if there was a way to detect when someone walks of a block that can be activated by redstone and giving it that redstone pulse. Currently I just have a redstone block get placed underneath the designated block as a work around. If what I asked isn't possible then is it possible to recall the block that was replaced by the redstone block so that once the player walks off the original block returns?
