I've got level 100 smithing but for some reason I can't improve Ahzidal's Boots of Waterwalking above the Epic level. I read on a wiki that the boots benefit from the Steel Smithing perk, but if that's true then why can't I improve it to Legendary?

Is this a glitch or am I missing some information here?

You can only get something to legendary with the "improve twice as much" skill perks without the armor/weapon/jewelry enchantments.

Wow, that really svcks. So if I'm making regular weapons and armor I would have to make it legendary before I started enchanting it, or else I wouldn't be able to get it to legendary? That seems ridiculously arbitrary.

seems that way, they going until Epic, but you can make enchanted set(s) and poison(s) for that.

Get some fortify smithing potions and neclace/bracers/rings whatever you can find it still seems to improve your skill even if you're at 100.

If you want to get hardcoe...

> Make a couple Fortify Enchanting potions.

> Drink potions, enchant five pieces of gear with Fortify Alchemy.

> Make a couple new Fortify Enchanting potions, and enchant four pieces of gear with Fortify Smithing and five more pieces with a stronger Fortify Alchemy

enchantment.

> Make a Fortify Smithing potion with your new Smithing/Alchemy gear.

> Drink potion, wear the second set of Smithing gear, make ridiculously powerful weapons

(sorry but i had a Network breakdown for a couple of minutes, so i am fine now.)
