[HELP] Item icon not appearing

[swordEnthusiast]

So the item I modded in appears in the game, but it doesn't have an icon and it just appears invisible. The item I used as a base was the Plated Longboots and I pretty much just duplicated it. I wanted to make a Boots of Swiftness item since my character is slow as hell. I fiddled with the Athletics multiplier, Combat Speed, Stealth and Weight and set it so that the item is sold by all armor vendors. It works, but there's no icon! It's just invisible and it irritates me a bit. XD The item's weight is still the base one, too, not the value I set it to. I also tried duplicating the Plated Longboots mesh, changing the name, and setting the item's mesh to that, but it didn't work either. Help, anyone?
