I voted "All Three", but I don't want it to stop there. I was a big, BIG fan of the equipment system in Ocarina of Time and I have been consistently very disappointed in its lack of use in the games since (Twilight Princess kind of had one, but it was lacking). I'm very fond of the idea of many types of equipment with many different powers, boots included. Boots are the "mobility" equipment.
I fail to see what this commotion about the Pegasus Boots being difficult or impossible to do in 3D is about. How is it
in any way difficult to implement the ability to charge forward in a 3D game? We already have the ability to run in Skyward Sword, so the charging would simply be a faster run with less or no ability to steer and an impact that damages or knocks things back. Some enemies would be designed to dodge or withstand this impact, creating strategy. I'd LOVE to be able to bull-rush my enemies, which is actually a fairly typical combat strategy of mine in any video game; extreme aggression and relentless assault.
The Pegasus Boots are definitely the item I want to see the most, but I want to see the other boots come back too
as well as new boots, same as I feel with all equipment items. Iron Boots are classic, basic, and generally useful. We could have them expand your strength or weight in combat as well or do the same thing they always do. As for the Hover Boots, a nice expansion to its ability to briefly hover over space would be if it could make you hover indefinitely or longer over
semi-solid surfaces. I'm talking water or lava mainly, but mist or other substances could work too. Now that sounds interesting doesn't it? I'm sure there are all kinds of new boots they can come up with too, plus other ideas for existing boots.
I was never a fan of the Iron Boots anyway. They never were very "magical" like so many other items that come from Hyrule. Just some metal boots that weigh a whole lot, I have trouble understanding just why someone would make something like that in the first place.
Steel-toed boots exist in real-life for protection purposes. Even in the context of fully metal footwear, it makes sense if you need armor, need to be weighed down (which could exist depending on unique jobs or tasks and this is how it's used in Zelda), and possibly other reasons. In Twilight Princess the boots allowed humans to face Gorons in wrestling matches, and they were also magnetic, allowing you to walk on magnetized surfaces. This implies they could have been mining equipment. There are possible explanations or practical uses, and there are ways to make them more useful and fun in-game.
