So I was fed up with how Blizzard hasn't fixed the problem with these boots looking like socks instead of how it's really supposed to look like (like the holy counterpart, Relentless Gladiator's Greaves of Salvation). I experimented a bit and found the error.
Anyway, here's what you need to do:
1. Get a hex editor if you don't already have one:
XVI32: http://www.handshake.de/user/chmaas/...load/xvi32.zip
2. Use it to open your itemcache.wdb in your /worldofwarcraft/cache/wdb/enUS/ folder.
3. Use the find tool to locate Relentless Gladiator's Greaves of Triumph.
4. You should see some code after the name, the 2 slots where I circled need to be replaced with 0000. When you are editing, make sure you click on the left panel before you start typing.
5. D9FE is where the code is supposed to be (I'm currently using D9FE, which is Wrathful). If you want it to look like Relentless boots, use 21F0 (code for Relentless Gladiator's Greaves of Salvation).
6. Make sure to save and you're done!

Small correction in the pic: I indicated in the picture that I was using Wrathful Gladiator's Greaves of Triumph's code, but I'm actually using the code for Wrathful Gladiator's Greaves of Salvation.
