Are the boots of speed overpowered?

Well met and all that.

The boots of speed are a nice pair of shoes, possibly the best item in the game, but they're a little too shiny if you ask me. They overshadow and deminish the monk and barbarian increased movement class abilities.
I think a ballance could be achieved by giving the item a once a day charge and limited duration, similar to how the cloak of algernon was adjusted.
